I made a donation to the Rocky Mountain Elk Foundation, and they sent me a Browning fixed blade as a token of appreciation. I was getting ready to sharpen it and noticed that in the directions that came with the knife showed it being sharpened at a 20 degree angle. I normally work my hunting knives at a 25 degree angle and my kitchen knives at 20. Any comments or observations? Have I been using the wrong angle on my hunting knives all these years?
