When you buy a knife, it does not come as sharp as can be. This is due to the fact that knives are mass produced and sharpened on the assembly line. It is near impossible to get a 100% perfectly sharp edge using a machine designed to sharpen hundreds of blades at a time. Even companies like leatherman that sharpen their blades by hand are doing so very quickly to be more efficient. To get the sharpest edge you must sit down and spend a little time sharpening and honing your knife using a nice sharpening kit. You can ALWAYS make a store bought knife sharper.
