Not my idea. billym mentioned it first in the thread, but it's a Benchmade so the policy applies. Sounds to me like he let the knife get to dull and it just needs a new edge. I'd use the Sharpmaker and not go for an acute edge. Making the edge too thin is the reason so many knives won't hold their edge. Do you really need it to shave with? I see so many guys who reprofile the edge so that they can shave their arms, but is that a realistic requirement for an EDC utility blade?
You can get a shaving edge with almost any angle.
That is just edge refinment... And it will make the edge(whatever the angle) last longer.
He could convex it and make it last a long time too...
