These are some sweet looking heads. I hope they release a left bevel at some point.

Not crazy about a 1in cut. The additional edges sure don’t look like they are made for cutting.
I hate to say it that head looks like it was designed for the test vs being designed to inflict tissue damage.
They show a deer supposedly shot with it. Also you can see the additional cutting edges actually make small cuts in the sheet metal. Just stating what I saw. Not sure if that picture of the deer was real. Not sure if the other cutting edges will make a difference in real life.

I was highly skeptical when I first saw these. However I guess I need to take the design more seriously.

If annihilator would release the C notch results of their chosen steel, that would be a great way to flex on the competition.

The scoops and double bleeders would do a lot to disrupt lift and prevent planing, which night be the reason for the consistent flight. I wonder how accurate they would be in a poorly tuned bow.

Each of the 4 scoop blades are probably 1/4" in height from center line. Add that to the 1" cutting diameter and it equals 2". Tissue trauma is tissue trauma. It doesn't matter if it's all on the same plane or perpendicular to the primary cutting blade. I work as a Flight Paramedic. I've seen people who have been stabbed once and I've seen people who have been stabbed twice. The people who were stabbed twice had more tissue damage and more blood loss.

But yeah, I can understand the skepticism of a 1" cutting diameter. Although, when we consider that there's two separate 1/2" cutting diameters perpendicular to the 1" cutting diameter, the ability to create trauma is there. The downside to that design though is, the shape of the entrance and exit holes isn't conducive to good blood trails. I've had great success with Annihilators in the past, but blood trails haven't been the easiest to follow. On an accurate well-placed shot, its never mattered though.

My current setup is Iron Will Wide 125's. Their main cutting diameter is 1 3/8" and have a 3/4" bleeder. Total cutting diameter is 2 1/8". I don't think 1/8" in total cut makes much difference ... but, the 3/8" wider main cutting diameter DOES create a larger entrance and exit hole, and the tearing that accompanies a well-placed shot results in a far better blood trail. A 1 3/8" wide cut vs. a 1" cut is more confidence-worthy for when the time comes and Mr. Murphy shows up.

The other thing about the Katana is re-sharpening. They're apparently advertised as tougher than A2 and with better edge retention, but easier to sharpen. You can't have both. A tougher, harder edge will be harder to re-sharpen. An easier to sharpen edge will not hold up as well. And I'm curious to see the process for resharpening these. In my opinion the sharpness of the bleeders is just as important as the main blades, and these bleeders look like they will present some challenges. I prefer to use sharpeners instead of flat stones. I kinda suck at sharpening things, and the sharpeners like the Work Sharp Pro Precision Adjust and it's predecessors have provided me the best results so far. I'm not sure if the Katana can be sharpened in that style of sharpener - maybe, maybe not.

Machined and secret. Molded designs would have folded in testing, and they're not a steel mill so they don't make their own. Refining iron into steel is only done on a huge scale.

The fact that these are less than $100 a set just means they're using a more common steel that hasn't been evaluated for broadhead applications for whatever reason.

Found it.

Looks like another test were Lusks heads receive a bunch of special attention before they get mailed to him....disappointing to say the least
I'm not loyal to John or Annihilator at all, but I think your take is unfounded. First of all, that's a low sample size to create a generalization. Secondly, there are other variables to John's testing that he hasn't isolated yet.

If you hand sharpen enough machine-ground edges, you'll know how inconsistent they get. Variation across a lot is normal.

Extra sharpening out of the box? Who cares? You're going to shoot it into a target a few times anyways before you hunt, and you should sharpen it again afterwards. Hunting-sharp out of the box is for mechanicals, not fixed heads. This really shouldn't be as important in John's testing as it is.

That's like saying you're upset a car review didn't have to do the break in period of 500 miles and an oil change, like everyone else does.

That's assuming it was intentional. I'm 90% sure John's technique on the BESS creates more favorable results. Not to mention that factory edges are notoriously inconsistent not just between blades, but sometimes on the same blade. You can have a 1mm section that's sub 100g, and another next to it over 300g. How quickly you add weight can change the shapness reading a lot as well. The same blade on the same machine can read anywhere between 100 and 300 from pushing speed alone, not even taking edge variation into account.

Everyone can, and does, bias a BESS tester one way or the other. Doesn't matter if they're aware of it or not.

It takes me at least 30 minutes to get a Cuththroat or Iron Will razor sharp after a kill, dirt shot, etc
I usually resharpen one practice BH before hunting season. And, one after each deer. Avg 3-4 bow kills each year with avg one miss on a jumpy doe. I thoroughly enjoy the process after a good kill.
