A Necessary Introduction

The preferred shape is that of a bevel, which is slanted from the edge. This results in a thin edge that allows for the knife to cut. Most knives have a double beveled edge, resulting a V-shape edge.
This edge is what does all of the cutting. The problem is that the sharp edge is pretty thin and can be pretty fragile. With all the work that a pocket knife does, this edge will eventually degrade. Damage to the edge can come form in microscopic chips or even blunting. This is why sharpening is needed on a regular basis.
The Right Tools

The coarser stones, which are usually around 200 grit, can make the edge come out quickly. Finer stones at higher grit counts are used to help polish the knife to get a shine and a sharper edge.

Once fully wet with either oil or water, the next step in how to sharpen a pocket knife with a wet stone is to properly position the blade. The bevel is the key to it.
