-These knives have a concave shape to the blade
-If the concave is shallow you can sharpen it with the standard 1" wide stones.
-If the concave is deep or has a sharp curve, then you will need the 1/2" wide stones.
-You can cut the bevel in with the 1" stones, but you will need the 1/2" stones to get a good finish.
-For practical reasons, purchase the stone you will be finishing with in 1/2".
-1/2" polish tapes are also available for a polished edge.
-If you are just going to use your 1" stone, it really helps to round the edges of the stones with a diamond, sand or silicone carbide.
1/2" stones available upon request
