In this review, I’m going to be covering a broadhead that has been around for a while. It’s one I’ve actually used in the field quite a bit and been fairly successful with. It’s called the Gravedigger.
The Gravedigger Hybrid broadhead overview
Let’s take a look at the design and some of the features of the Gravedigger Hybrid head (it’s called a “hybrid” because it has both fixed and mechanical blades). Then, I’ll show you how it performed when I put it through my standard array of tests.
The cutting diameter of the Gravedigger Hybrid’s fixed blades is 1 inch. In the closed position, the mechanical blades are ½-inch. So, just in the closed position, if the blades were not to open at all, it would be an inch and 1/2 of a cut, which is no slouch of a cut.
But the mechanical blades do open. They open really well, in fact. They’re not held in place by an O-ring or a retention clip, but rather just by friction, and that’s adjustable with a small Allen bolt.
The blades of the Gravedigger are made out of a 416 stainless steel. The ferrule is a 7075 aluminum. It’s a pretty vented blade, but it’s still is a good stout aluminum, and the tip is a hardened steel, really stout, chisel tip.
I couldn’t find any information listing the blade thickness, so I used my micrometer to measure. The fixed blade measured 0.039 inches thick and the mechanical blades were 0.032 inches thick.
Gravedigger broadheads testing
I was eager to see how this head performed in my tests. I did not test it for long range flight, because I know it flies really well.
I consider it like a mechanical in terms of flight in the closed position, and I don’t test mechanicals for long range flight, because they all fly really well, even though this head has the little one inch fixed blade. I know it flies fantastic.
I tested for edge sharpness and retention, for penetration, and for durability.
Let’s see how the Gravedigger performed.

Ballistic Gel Penetration Test
The Gravedigger penetrated 6 and 1/4 inches through the foam and ballistic gel.
In this review, I took an in-depth look at the Muzzy Trocar broadheads.
I know, the Muzzy Trocar head is not new. It has been around for a long time, and I’ve used it in some of my other tests, but I’ve never done a comprehensive test on it alone. So, that’s what I did.
Muzzy Trocar design specs
The Muzzy Trocar and it’s a pretty cool-looking head. And as you can see, it has a short overall profile, which is going to aid in flight.
It also has offset blades. In the above picture, you can see that the blades are arranged in a right helical offset pattern, which helps with rotation and aids in flight, keeping them more accurate, due to a spinning effect.
And, then within the animal or any medium it hits, the blades will continue to rotate. It’s going to create a decent wound channel inside the deer or other animal as well.
The ferrule of the Trocar is one-piece construction of steel, with a really nice, small, but stout tip.
The blades are all steel as well and they’re 0.035 inches thick, with a cutting diameter of 1-3/16 inches.
So, it provides a pretty decent size cut, just one 1/16 of an inch bigger than the standard 1-1/8 inch cut. This head is 100 grains.
Now, another thing about them is they have a 3-point blade retention system. The blades are held in place at three different points just to make sure that you don’t lose a blade, even on hard impacts.
These heads fly incredibly well. They come with a ballistic match point which looks just like the regular head’s shape that’s basically a practice head. It flies just like the regular head would fly.
They are also extremely forgiving. Now, I realize that a lot of heads fly very well. My bow is really well-tuned. I can pop balloons with fixed blades out to a 100 yards, but this is on the extra forgiving side for sure. So, I love that.
On the downside, I don’t like that it’s just a metal injection molding. I’m not a huge fan of that. It’s still good, and it’s better than a lot of aluminum heads, but it’s not as good as machined heads (of course, it would cost a lot more if it were a machined).
However, it is still a solid steel and it has a two-piece ferrule. It is a few different composite pieces of steel, but it is, in essence, 100% steel.
In the first test, I shot the DeadMeat through a 3/8” piece of plywood. This is my favorite thing to do with mechanical broadheads, so that I can see how well they deploy upon entrance. It also helps me see how well they penetrate and hold up to the plywood. In many ways, it’s similar in consistency to bone.
If they don’t hold up to plywood then I’m not going to be hunting with them for sure.
So let’s see what happened with the DeadMeat in the 3/8-inch plywood.
In the testing, I used a footed Hexx 330 arrow with a total weight of 500 grains and I shot it out of a Hoyt Carbon Spyder 30 at 73 lbs.
Plywood penetration test
After shooting into the plywood, the blades were not near as sharp. So, they dulled significantly such as metal injection molded blades will often do.
Something to watch for
I have known someone who had one of the three heads in his pack that had blades that would not deploy at all. Upon further inspection, he found that there is a groove that the blades slide up and down in.
This groove can contain small burrs, which is what was preventing his blades from opening. He talked to G5 about it, and of course, they replaced them. But, that would be something to test before you shoot them to be sure the blades are sliding and opening effectively.
