Single sided stones
Sharpening stones with single grit to sharpen several sharp edges.
You can find the grain suitable for roughing, refining or polishing the edge of your knife.
The higher the grain number, the finer the grain.
Coarse-grained stones (up to grain 400) can be used to shape the blade of a blunt knife.
The average 600 - 1000 grit can be used to finish the edge of your knife.
The 1500 - 2000 - 3000 grits allow you to polish the wire.
With 4000 - 5000 - 6000 and 8000 grits you can make a cutting edge of your knife that is very shiny and slippery, a perfect cutting edge.
