Fletch Fight | FOB Archery vs Vanes

Over the years I had heard about the “FOBs” from FOB Archery on various archery forums. I learned that FOB stands for “Fletchings Only Better.”

But what was the story behind this new product, and would it really work better than fletchings or vanes?

The History of FOB Archery

The FOB is made of nylon and has “fletchings” that are at a 4-degree off-set.

The FOB was designed by an aerospace engineer named Paul Morris. He designed it based on the concept of aerodynamics. He believed there was a away to improve upon the old fletching that Native Americans and people all over the world had been using for years and also in competitive archery. At the time, the FOBs were known as Starrflight FOB.

But then, in July of 2018, three business partners purchased the company from Morris and rebranded it to FOB Archery.

FOBs At First Glance

I finally got around to testing the FOBs. I have to be honest, when I first started reading about them and saw them, I was like, “Really?” My B.S. meter was going off a little bit.

But, I decided to give them a try.

The FOB is made of nylon. It looks simple, and in some ways, it’s exactly that. But in other ways, it’s very meticulously designed.

It simply slides onto the end of the nock. Then you insert your nock into the arrow shaft and you have essentially fletched your arrow. It’s that simple… and it’s fast.

No glue. No time. Just boom! And it’s done.

Keep reading for an in-depth look at the FOBs to find out if they’re right for you…

An In-Depth Look

The circular ring around the FOB is thicker in the front than it is in the back. It’s an air foil design that aides in the stabilization and flight of the arrow.

fletchings only better
The FOB, although just a small piece of nylon, is precision crafted to give arrows proper in-flight stabilization.

The three little “vanes” are at a 4-degree offset. In effect, very And then these vanes if you will, the three little vanes, they are at a 4-degree offset.

The FOBs claim to be more accurate in a cross-wind than fletchings. The theory is that the cross-wind will blow a fletched arrow more off-course due to the larger surface area on the back of the arrow.  

The combined with the air foil design, the offset vanes allow for greater spin. With the thicker front portion of the ring, and the thinner part in the back of the ring provides 360-degrees of stabilization.

Offset fletched vanes will rotate, but technically not the 360-degrees of stabilization that the ring of the FOB provides.

I should note that the blazer vanes I typically use are different than what most people use. I use a 4-degree helical setting. So, they are put on with a 4-degree helical using an Arizona EZ Fletch.

That gives you the fastest rotation that you can get with blazers.

Sometimes people use the blazer vanes with an offset at 3 or 3-1/2 degrees. Some will just buy them from the factory in a straight position. But, when you put them on with a helical, they spin a lot better and you get better groups.

I tested the FOBS compared to the 4-degree helical blazers to see how well the fly and group. I tested indoors and outdoors with field points and also outdoors at long range using broadheads.

With Fixed Blade Broadheads at 80 Yards

I shot the FOBs vs Blazer vanes at 80 yards outdoors with fixed-blade broadheads.

Ballistic Gel Testing

ballistic gel test setup for fobs
This test consisted of ballistic gel with MDF board in the back of the setup.

Next, I did some testing into ballistic gel, shooting a regular vaned arrow with the Blazers and an arrow with a FOB on it.

I wanted to see two things. First, I wanted to see how the penetration was affected by the fletching and by the FOB. Secondly, I wanted to see how effectively the FOB bounces off the gel when it is contacted.

I first shot the FOB and then the Blazers. On impact, the FOB bounced right back to my feet (about 4-5 yards).

FOB Penetration vs Blazer Vanes

The vaned arrow went through the ballistic gel and simply landed behind the gel block. It didn’t stick at all into the layer of MDF.

However, the bare shaft that had the FOB on it continued to fly through the gel and not only stuck into that layer of MDF, but actually penetrated all the way through it and popped out the other side and made a big dent in the next layer of MDF.

Notice that the arrow tip with the FOB on it penetrated better than the one with the Blazer vanes, because the vanes had to pull through the gel whereas the bare shaft just slipped right through.

After putting the FOBs through every test that I can think of, I was pleasantly surprised. Actually, I was borderline shocked by how well they performed. They passed every test I have.

Pros and Cons of FOBs

Here is a summary of what I think are 7 pros and 7 cons to be aware of when considering using the “FOBs” from FOB Archery.

  The Pros:

installtion of fob
Installation of a FOB takes literally seconds.
  • Speed of fletching: You can fletch a dozen arrows in less than a minute instead of about an hour. And, you can do it in the field just as quickly.
  • Accuracy: FOBs are every bit is accurate as a 4-degree helically attached Blazer vane. That’s pretty darn accurate. So, I know that my vanes at a 4-degree helical vanes are more accurate than straight vanes and even more accurate than offset vanes at long distances. The FOBS group just as well.
  • Drift resistance: The FOBs are able to handle wind drift amazingly well. They are much less affected in a heavy crosswind than Blazer vanes or other vanes. That’s an important asset when you are bowhunting out West or shooting at long range.
  • Penetration: The superior penetration of arrows with FOBs surprised me. Because the arrow didn’t have the drag of the fletching, it just zipped through the ballistic gel and penetrated through a half inch of MDF. The arrow with the Blazer vanes did not stick into the MDF at all. That’s quite a bit difference in penetration. The lack of drag makes the difference. That was impressive.
  • Durability: I am very impressed with the durability of the FOBs. I shot them a couple hundred times. I’ve hit the FOBs with the tips of other arrows a number of times (they call this a “FOBinhood” when you stick one arrow inside the FOB of another arrow on the target). The FOB got a little dinged up at times but I have yet to break one. And, even when they are dinged up, they still work fine. TIP: If you are in a dry climate, you can soak the FOB in water, inside like a Ziploc bag or container for a day, they get even a little more pliable. This will help them become even more durable than they already are.
  • Quick Change Colors: Another little thing I like about them is that I can change colors without having to strip everything down off of a previous arrow and put on another one. I can just pop off the FOB and add a different colored one.
  • Ability to use arrows with bare shafts: Another strength of the FOBs is that you can use bare shafts. One of my best archery buddies, Shane Chuning, taught me that to always have a bare shaft in my target quiver so that I can test the tuning of my bow. This helps me test my own personal form. And, nothing reveals imperfections in form and tuning like a bare shaft. So, I always try to designate one arrow like that. With the FOBs essentially all your arrows can be bare shafts. You just pull that off and then you got bare shafts. You put the nock back in and you can tune a whole round of bare shafts and then put the FOBs on and shoot a whole round of fletched ones. So, that’s definitely a plus as well.

The Cons:

So, now that I’ve covered the 7 advantages of FOBs, I’ll cover what could be considered disadvantages:

  • Must use a drop-away rest: To use FOBs, you must use a drop-away rest. They will not work with a prong rest, because the FOB won’t clear it. You also cannot use something like a whisker biscuit, as the FOB would come off as the arrow passes through it.
  • Cheek Interference: If your anchor point is way back, or at the back of your head, the FOB could catch your ear. That wouldn’t feel nice. Or, if you mash your arrow into your face, or have a large beard, you may have a problem using the FOBs. For me, the anchor point is not an issue with FOBs. With the way I anchor, I didn’t notice it, even with a heavy mask on that I use during cold weather. So, this may be an issue for you, depending on where you anchor.
  • “FOB Pinch”: Another con would be a “nock pinch” of sorts. Some individuals with really long draw length that shoot bows with a short axle-to-axle length could experience this. Because the FOB is so far back on the shaft, the string could pinch the top and bottom of the FOB at full draw. If that’s the case with you, the FOBs wouldn’t be right for you. FOB Archery is supposed to be coming up with a solution for this in the near future.
  • In-Flight Sound: Some individuals that have used the FOB say the sound is an issue. I compared them in flight to the sound of my 4-degree helical blazers, which are louder than straight or offset Blazers. To me, the FOBs sound about the same as the Blazers. I couldn’t tell a difference. I even tried a decibel meter, putting it a halfway down range to try to see if they pick up a difference. The decibel meter wasn’t sensitive enough to pick up any difference between the two. Honestly, I don’t worry about arrow flight noise. Instead, I worry about bow noise and human noise at the shot. My reasoning is that bugs are zipping around deer all the time. Birds are flying by. Leaves are falling. I don’t believe the arrow flight noise is an issue worth being concerned with and I’ve never had a problem with it during a hunt.
  • Finding Arrows: Another concern is from those who use lighted nocks. The thought here is that during a pass through shot, the FOB pops off, taking the lighted nock with it. So, you would find your nock easily enough, but not necessarily your arrow. If the arrow stays in the animal, well, you’re going to see it running off with a lighted nock as normal. One way to address this concern is to use a reflective wrap. And I find those just as effective as a lighted nock at finding your arrow because you shine a light on it and it lights up like a Christmas tree. I like to use a lighted nock for videoing, but a reflective wrap really helps you in finding that arrow. So, while some consider this a con, I do not.
  • Weight: Adding the FOB to an arrow makes it 8-10 grains heavier than using Blazer vanes. That’s very minimal in my mind. It’s kind of the difference between using a lighted nock or not, which doesn’t really affect my shooting accuracy unless I’m out well past 60 yards. In that case, I simply sight in my bow for lighted nocks, and the FOBs hit right where my lighted nocks hit. So, again, this “con” is a non-issue for me.
  • Cost: One other concern that people have expressed at times is the cost. I wondered about that too. So, where do FOBs fit in cost-wise? They are about $2.25 each. You get a 12-pack for $29. So, they are more expensive than just getting vanes and attaching them yourself. But, they are less expensive than paying a bow shop to attach your vanes. They are also less expensive than buying the shrink wrap vanes and putting them on.

Conclusion

In conclusion, I really like the FOBs. They passed every test I could think of. I’m ready to take them into the field! Let me know your thoughts or any questions you have on this alternative fletching in the comments below!

afflictor broadheads

Afflictor Broadheads Review (Hybrids)

I had been wanting to test the Afflictor Hybrid broadhead for a while. So, when I finally got my hands on some I was excited to test them out.

Afflictor Hybrid Construction

I have used tested and used other hybrid broadheads on the market, but the Afflictor heads are different than other designs. They have a main cutting tip that’s about 1/8-inch thick, made of 420 stainless steel that is extremely thick and sharp and will not fold over.

They also have a feature they call a “drive key,” that also functions as a bleeder blade that opens up the main blades, but also cuts extra tissue.

Afflictor 1-3/4″ Hybrid vs Afflictor Ultraviolet | The differences

On the 1¾-inch Afflictor Hybrid, the drive key has little prongs on it. They are designed in such a way that if they hit hard bone, they will shear off by design, so that the head can continue to penetrate. In fact, everything about this head is designed for penetration.

Afflictor also offers a head called the Ultraviolet, that is purple in color. At the time of this publication, it is the only purple broadhead on the market.

The Ultraviolet has a little bit different design. The main tip of the Ultraviolet is longer and more swept than the original Afflictor Hybrid. Due to that design, it has a little bit better penetration.

Another difference is that the Ultraviolet has non-shearing drive key that functions as a bleeder blade. So it’s a half-inch wide and will open up the blades and continue to cut tissue.

afflictor ultraviolet vs nap killzone penetration
Penetration test using Afflictor Ultraviolet, Afflictor 1-3/4″ Hybrid and NAP Killzone.

With the Ultraviolet broadhead, you get a 1¾-inch cut and plus the ½-inch bleeder, for a total of a 2-inch cut.

Afflictor also makes a 1½-inch  model of this as well and it also has the ½-inch bleeder, for a total cut of 2 inches.

Both versions of this broadhead fly extremely well. They are both 5/8-inch thick in profile, which is like most other mechanical heads on the market. The specs and construction are top-notch.  They also spin very well in flight.

On impact, the drive key comes down and the blades open. There is also a pretty strong o-ring that keeps the blades from rattling during flight.

The NAP Killzone is my standard for comparison testing, as it’s been around for many years. It’s a really reliable and super strong head. However, it doesn’t penetrate very well, so anything I test should penetrate better than the Killzone.

For comparative purposes, I tested penetration and durability in comparison to the NAP Killzone broadhead.

Penetration Testing | The Setup

This shows the initial cut size of the Afflictor Ultraviolet and Afflictor 1-3/4″ Hybrid vs. the NAP Killzone.

If you have seen any of my broadhead tests on mechanicals, you know that when I do comparative tests, I don’t test them on animals. The reason I don’t do this is because they don’t hold any value.

Different bones have different densities and bone geometries. Every animal is different. In addition, shooting angles on animal bone could have varied results, which would not provide good insight into how the broadhead truly performs.

So, I use a uniform medium to simulate animal anatomy as best as I can. I use carpet on the front and the back to simulate animal hide. I also use a rubber foam to simulate tissue and ½-inch plywood in the middle to simulate the bone.

Then I use a few more layers of rubber foam toward the end for padding, followed by another 3/8-inch plywood at the end just in case it were to make it through all of that.

I also have a thin sheet of cardboard in the very front to get a visual on how well the heads deploy on impact.

In the angled shot test, all three heads penetrated, but the Afflictor 1-3/4″ Hybrid slid on impact.

Penetration Test #1

I first tested the Killzone head, followed by the Afflictor 1¾-inch head and the Afflictor Ultraviolet.

In the penetration test, the Ultraviolet out-penetrated the others by a wide margin. Of course, the Ultraviolet it has that more swept initial tip and also has the 1½-inch cut, and that solid drive key. Those factors made all the difference in this penetration test.

Take a look at the Afflictor 1¾-inch cut broadhead. The 1¾ inches plus the ½-inch bleeder provides 2¼ inches of cut. The blades came all the way through the ½-inch plywood after going through the carpet and the rubber mat and the cardboard.

The NAP Killzone tip came through the wood, the blades did not. The NAP has a good, long tip that’s really tough. But the blades didn’t do any cutting on this test. All the broadheads in this test held up well in the penetration test.

The NAP Killzone broadhead broke off at the ferrule during the angled shot penetration test.

Initial Cut Size

When inspecting the opening cut, the Ultraviolet opened 1½ inches from the main blades and then ½-inch from the bleeders and the bleeders stayed intact.

The 1¾-inch Afflictor Hybrid opened 1¾-inch on impact and then had the drive key bleeders cut  a ½-inch and those stayed intact as well.

The NAP Killzone advertises a 2-inch cut, and it actually cut a little over two inches (2-1/4 inches).

So, all the heads in this test opened well.

Penetration Test #2: Angled Shot

In the next test, I performed a steep angled shot.

I first shot the Killzone and it stuck right in. Then, I shot the Afflictor 1¾-inch Hybrid. It stuck in, but angled off a bit. Lastly, I shot the Afflictor Ultraviolet.

In the diagram below, you can see that the Killzone and the Ultraviolet penetrated through the back of the wood. The Killzone point come through the wood but not the blades. The Killzone also broke off at the ferrule and broke my arrow.

The 1¾-inch Hybrid went through all the layers of carpet and foam and cardboard and made a deep cut in the wood, but it skimmed across the top of the plywood.

Penetration Test #3: Afflictor Ultraviolet into 22-gauge steel

In this test I shot the Afflictor Ultraviolet into 22-guage steel, backed with a 3/8-inch sheet of plywood, a ½-inch sheet of plywood, 4 rubber mats and a Rinehart target behind it.  

Because I didn’t want to break another arrow, I used the Mammoth Arrow by Bishop Archery, which are guaranteed for life.

The Ultraviolet went through the 22-gauge steel plate and poked through the back of the 3/8-inch board about a ½-inch. The tip held up really well.

The blades of the Ultraviolet not only went through the steel plate, but they opened up as well, which is very impressive. When I have shot other heads into steel and plywood in this manner, they only hold up when the blades don’t reach the steel plate. But here, the blades held up and even opened up inside of the steel plate. Even the drivel key was still intact.

Conclusion

In this Afflictors broadheads review I learned a lot. I didn’t really know what to expect from these heads. But, I have to say I was impressed. They have a very low profile and will fly really well.

I didn’t expect them to open so well, penetrates so deeply and hold up as well as they did through that medium.

The Ultraviolet’s penetration was extremely impressive, especially on the angled shot, as they not only penetrated the steel plate and the plywood, but also deployed the blades.

If you are looking for a fool-proof hybrid mechanical head, the Afflictors are going to fly like a dart and hold up well so you can kill some big game!

sevr 1.5 and 1.7 inch broadheads

Sevr Broadheads Review | What You Need To Know

-By John Lusk

In this broadhead review, I tested two new broadheads from the same manufacturer; The Sevr 1.5 and 1.7-inch broadheads.

Sevr Broadhead Offerings

Sevr originally came out with a broadhead that had a 2.1” cutting diameter. It was a great head with fantastic flight and it was tough. But, the penetration is about what you would expect from a 2.1” broadhead and it was a bit lacking in kinetic energy for my purposes.  

For a deer, or even for smaller game like turkey, if your number one goal is a big hole, the 2.1” Sevr is going to deliver. But to round out their lineup, they’ve come up with two additional offerings.

sevr broadheads 15. and 1.7 inch diagram
The 1.5-inch and 1.7-inch Sevr broadheads look the same in shape, but with some subtle differences in head and ferrule composition.

Sevr 1.7-inch Broadhead

To compliment their original broadhead, Sevr introduced a 1.7” head. It has a stainless steel tip and it has got a good grade aluminum ferrule. It has rear deploying blades that lock in place, which I love.

The 1.7” cutting diameter provides decent penetration and is a good all-around broadhead offering for pretty much any kind of game.

Sevr 1.5-inch Broadhead

Sevr also introduced the 1.5-inch head. The 1.5-inch operates just like the 2.1-inch with a few design differences.

On the 1.7-inch head, the tip is not quite as big as the 1.5-inch head and also has a smaller ferrule.  The 1.7-inch head only comes in a 100-grain and is a little cheaper, while the 1.5-inch head comes in a 100-grain as well as a 125-grain.

Sevr 1.5-inch and 1.7-inch heads | The details…

Firstly, just as the name implies, the 1.5-inch head has a 1.5-inch cutting diameter. Also, the ferrule and tip on the 1.5-inch head are titanium, as opposed to the stainless steel tip and aluminum ferrule of its 2.1-inch predecessor.

The blades of the 1.5-inch head are stainless steel and lock into place just like the 2.1-inch head.

The 1.5-inch head is designed for big-bodied, heavy-skinned animals. It is also better for longer distance shots, due to the smaller cutting diameter.

Although the cut is 1.5” wide, the chiseled tip itself is approximately 5/16-inch wide. So, with the 1.5-inch width cut in one direction and the 5/16-inch wide tip cut in the other direction, you get a total of a little over 1-3/4 inches of cut with a 1-1/2-inch hole.  

Pricing

Sevr has a direct-to consumer approach, so you can only order them from their website. You can purchase them by the eaches, but you can get a better deal if you buy higher quantities.

At the time of this article’s publishing, the 1.7-heads are $11.99 each. The 1.5-inch head is $13.99. The 1.5 is more expensive due to the titanium head. You can purchase at SevrBroadheads.com

Blades and cutting features

I love the way the Sevrs work. They have two small “wings” that are exposed during flight. When they come in contact with an animal, they actually “pre-stretch” the hide (skin) as the blades deploy. In theory, since the blades are rear-deploying, not only do you get a 4-cut entry, but you get a bigger cut.  

>>Hunting & Fishing Shirts with a story

The heads of the Sevrs also lock into place. So, unlike a lot of mechanical heads that can close down if there’s not a certain amount of pressure, these heads lock in place and they stay that way in the animal.

Because they lock in place, they will not give a smaller cut than they do at their full deployment. The blades will go back into pre-deployment position when removing from the animal, but will still lock back down in deployment position.

If you’ve ever shot a broadhead into a deer or other animal and hit bone, it typically deflects off course. But, the great thing about the Sevrs is that the will rotate to one side if they come they come into contact with bone or a hard medium like a rib. The blade will simply fall to the side that encounters the bone, allowing the other blade to continue cutting and still keeps the broadhead on track.

This feature helps increase the chances of getting a good exit and getting better penetration of lungs and other vitals when the head encounters bone. And, because the blades stay locked even as they rotate, they just “dance” around the bone.

sevr blade rotation
Sevr blades will rotate when coming in contact with bone or other hard surfaces, which helps prevent bending and breaking of blades and keeps heads on course.

Another nice feature to the Sevr broadheads is that when there is heavy pressure on the blades – the type of pressure that might bend or break both blades – they compressed ever so slightly to absorb some of that impact. Because of this feature, they difficult to break.

Blade Thickness

The 1.7-inch heads have a blade thickness of 0.035-inch thick. The 1.5-inch heads have blades that are 0.032-inch thick. Both heads have all the same features, locking in place and pivoting around bone, staying on track.

I was excited that they came out with a 1.7 and came out with a 1.5 because the 2.1-inch was just a little bit much for me to be able to be confident that I would be able to get a pass-through on an animal.

Although I knew I would get a big hole, I needed to be confident that I would get pass throughs. And, when hunting large animals like elk or bear, I want to be sure I get deep penetration.  

Blade angle and overall cut

Another thing I like about the 1.5-inch head versus the original 2.1-inch head is that the blade angle is much less. So, penetration is not only better because of a smaller cutting area, but it’s also better because of the smaller angle.

The same with the 1.7-inch head. While it has a slightly larger cutting angle than the 1.5, it is still less than the 2.1. So, the 1.7 also gets better penetration, not only because of the angle, but because of the smaller diameter cut.  

Now, you might think, “Oh, 1.5 or 1.7 inches is kind of small.” But, there are not many fixed heads that have a 1.5-inch cut. They might have a combined 2-inch cut, with 1-inch one way and 1-inch the other way. But, what I have found with broadheads on game animals is that the wider a cut, the more effective bloodletting you will get.

On three and four-blade broadheads, although you may get more total tissue cut, you get a smaller cutting diameter. And, smaller holes tend to get plugged up easier with organs blood and tissue, resulting in less effective blood trails.

But, when you get a wider cut, even like a 1.5-inch, the hide and wound tend to stretch open as the animal moves, producing better bloodletting. Of course, with the 1.7, you would get even more. With the 2.1-inch head, you’re going to get a lot of bloodletting, but you are going to compromise penetration to do so.  

So, with the new Sevr lineup, you have something for everyone. But, what I really wanted to see was… how do they fly? They are really the same heads, so I just tested the 1.5-inch.  

Sevr flight

sevr broadhead in target
The Sevrs fly just like a field point, providing great accuracy, even at long distances.

When it comes to target shooting the Sevr heads, there is a feature that helps them stand out. Each head comes with a small set screw, so that when you shoot, the head stays in a closed position. Because the blades do not deploy, they don’t touch the target at all. It’s very nice on your target and on the head itself.

So, in essence it makes the actual broadhead a practice head, and is easy to pull out of the target. Just be sure that when you hunt, you have removed the set screw, or the blades will not deploy.

Penetration and durability testing

For my penetration and durability tests, I shot the Sevr heads through 1-2-inch layers of MDF, with a foam mat in the front. I also shot them at a 45-degree angle on the MDF. After those tests, I shot them into a steel plate.

For testing, I shot the Bowtech SR6, set at 72 pounds, on the comfort setting. The arrows I used with the heads are the Bishop Mammoth FOC King, bsecause they are the most durable arrows made. These tests really put the arrows through the ringer and yet they don’t get damaged, as they are incredibly resilient.

MDF Board Penetration Test

I shot the 1.5-inch, 125-grain head and the 1.7-inch, 100-grain head into the MDF. Both broadheads penetrated all the way through the first board and then stopped into the second board.

In the back of the second layer of MDF, the 1.7-inch bulged out a little bit. The 1.5-inch bulged out quite a bit more.

On the entrance hole, both deployed upon impact even with the soft pad over the first board and the cuts are exactly as advertised.

The 1.5-inch head opened up to 1.5 inches. And the 1.7-inch head opened up to 1.7 inches exactly.

45-degree angle shot into MDF

I set up two MDF boards at a 45-degree angle and shot both the 1.5 and 1.7-inch heads into it.   

Both heads penetrated precisely straight through. There was no sliding off the 45-degree angle board at all. And, the penetration was great for both of them. You see the top one was the 1.5-inch, the bottom the 1.7.

Steel Plate Penetration Test

Because these heads held up so well in the MDF testing, I also shot them into a steel plate to evaluate what would happen.  

I honestly wasn’t expecting them to hold up that well after all those other MDF board shots. But, they went through the steel plate and then through the second board.

You can see that the 1.5-inch at the top, blew all the way through it. And you can see the tip of the 1.7-inch, 100-grain, sticking at the bottom.

Here are the heads after going through the initial two layers of MDF and then another layer of MDF and an angle, and then a layer of steel plate and then another MDF, half inch MDF. All of them were half inch MDFs. And they both held up extremely well.

On the 1.5-inch, there was zero damage to the tip. The blades took very little damage, incurring only one nick. (The nick at the bottom is part of the design that holds the rubber bands in place.)

As for the 1.7-inch, they too held up really well, receiving small nicks both blades from the steel plate test.

Overall, the Sevr heads held up really well, including the blades, tips and ferrules.  

sevr steel plate penetration
Both the 1.5 and the 1.7-inch Sevr heads penetrated the steel plate and the first layer of MDF.

Conclusion

When I first heard the Sevr broadheads were hitting the market, I had a lot of hope that they penetrate well and hold up well with the changes made to the new models. These heads have exceeded my expectations.

In terms of flight, I knew they would fly extremely well. And, they fly as good as any mechanical head I’ve ever tested. They are like a field point in flight, flying right up there with the very best.

In terms of penetration, they were excellent, maintain outstanding durability as they were shot into 4 total layers of ½-inch MDF, a steel plate and foam mat.

So the Sevr 1.5 and 1.7-inch are really a good heads for bowhunters to consider for various animals.
