Depending on what shape the knife edge is in when sharpening I go through this routine. Most of my knives have a convex or micro convex edge but you can sharpen any knife just adjust the angle.
> 400 grit emery paper on a mouse pad. (The mouse pad I use has a "firm" top.) This can be used for a knife or axe that is in bad shape.
> 600 grit emery paper on a mouse pad.
> 1100-1200 grit emery paper on a mouse pad. If the knife is in good shape I start here. At this point an axe can be razor sharp if it's made out of good steel.
> Using a two sided paddle strop with black compound, 3,000 grit.
> On the other side of the strop use white compound, 12,000 grit. Label the strop on each side black or white so you don't mix the compounds.
I have a few Bark River Knives and Ahti Knives that are made in Finland that I can get razor sharp using this method.
The paddle strop and compound can be purchased from most Bark River Knife distributors.
