Just in case you want to know how to use an Edge Pro Apex sharpener, Nutnfancy offers this 20-minute epic. Actually, make that if you want to know how Nutnfancy uses an Edge Pro Apex Sharpener. While this sharptacular is mercifully short by NF’s usual standards, it’s about 13 minutes longer than the official demo. Or this excellent 10-minute knife-sharpening vid. Personally, I have zero tolerance for epic how-to videos. And I have a Zero Tolerance knife. I ship it to them at my expense, they sharpen it, and then send it back at their expense. Works for me.
