Last night I took a Stinger that has been used to take a deer and sharpened it. I use a Gatco kit. The kit uses a clamp and hones that follow different angles. I used a marker to make the edge black and found that 19 degrees would work best. I used course, medium, and fine to work the blade. At that point, it would not shave hair. I then hit it with an AccuSharp as light as I could for 20 passes. After that, I could shave hair. To me that is sharp. My question is, how do you test your heads to make sure they are hunting sharp?
