NOTE: I sent the heads I tested back to the manufacturer and he had the hardness tested. Turns out they had a Rockwell of 48...and it was supposed to be 55. Glad to have discovered this error. He's having the hardening process changed for future productions. Once I get the new ones, I'll re-do the steel and hardness test.
On a related note, if you use a Stay Sharp Guide 35 degree single bevel sharpener--they hold up WAY better than the present 20 degree bevel--even with this softer steel.

TUFFHEAD has a great reputation for their traditional archery broadheads. Since Jason "Wojo" purchased the company in 2019, they now have crossed over in the compound bow broadhead market as well, with their new Evolution Series. This is the test of their 2 blade, single bevel, 200 gr head. I will be testing their 3 blade head as well, in the future.
This head is machined from S7 tool steel and coated as well to prevent corrosion. The blades are .070" thick and the bevel angle is 20 degrees.
I have a new test for edge sharpness and edge retention, using the Edge on Up Sharpness Tester. I test it out of the box and then again after Penetration Test 1, to see the edge retention. I also have a different test for flight--shooting one field point and two broadheads at 40 yds to see how well they group. And then I have a new overall Lusk Grade that I assign to each head--they receive anywhere between Zero and Ten Golden Arrows.
I have also picked up a new sponsor with my top recommendation for Broadhead Sharpening. [ Ссылка ] The support I get for that has helped me improve my channel.
Here is my sharpness scoring scale, using the Edge on Up Sharpness Testing Machine:
First of all, what are some common scores for other edges? Here are some examples:
A butter knife takes 2000 grams of pressure to break the co polymer wire.
A new high end cutlery edge takes approx 375 grams of pressure to break the wire.
A utility razor blade takes approx 200 grams to break the wire.
Based on the many broadheads I have tested, here is my scoring scale:
Out of the Box Sharpness:
0-200 gr: 10
201-300 gr 9
301-400 gr: 8
401-500 gr: 7
501-600 gr: 6
601-700 gr: 5
701-800 gr: 4
801-900 gr: 3
901-1000 gr: 2
1001-1100 gr: 1
1101+ gr: 0
Edge Retention: Sharpness difference after Penetration Test 1:
10 minus 1 point for every 50 grams of sharpness difference. For example, if the initial sharpness was 400 gr of pressure and the sharpness after Penetration Test 1 was 450, the head would receive a 9 for Edge Retention Score.
