Did my ASH-2 at 20 degrees, probably a bit much and would probably go back to 25 if i could. BUT 20 degrees will cut like a Sum-Bitch, just ask the ER Doctor who glued me back together!
Ash-2’s are awesome. That’s a good angle for a smaller knife (or a medium sized knife like an ash-2) that won’t take a ton of abuse, but not for a chopper. At least in my experience.
Yeah, I tend to try not abuse my tools. I can see it happening, but I try not to.
