After reading Dr. Ashby's report on single bevel broadheads.(right after I finished the last batch of double bevel heads)
I just had to make some single bevel heads. It just makes so much sense. I will test both to see if I get his results.
After making the first set of single bevel heads, I made a new set with a longer profile.
Then I fooled around with a longer version.
This is the latest design and the one I hunt with now.
