KUROMAKU is the world's first set of color-coded sharpening stones, each color representing a different grade of coarseness. The storage case makes it easy to carry the stones, and can also be used as a sharpening base. These stones are waterstones but can also be used as oilstones.
The stone is fired at a high temperature with a mixture of abrasive and a clay binder. It is 8-1/4" x 2-3/4" x 5/8". The case has rubber feet to help prevent slippage.
These “Splash and Go” stones do not absorb water and do not need to be soaked. Shapton Traditional Stones are often called the Shapton Pro or Professional Stones. Each name refers to the same Shapton series of stones.
These stones are easy to use, no need to wait for them to saturate, some of the fastest cutting stones on the market, and these stones are hard wearing, needing infrequent flattening.
White #120 - Extra Coarse
The White #120 stone is formulated for quick steel removal. It can quickly sharpen chipped or pitted edges. The scratch pattern will be coarse but very consistent.
Orange #1000 - Medium/Coarse
The Orange #1000 is a very popular intermediate stone. Great for moderate stock removal. This stone is good to use prior to polishing.
Wine #5000 - Fine
The Wine #5000 stone is the first polishing stone. It can still remove some metal but is primary a polishing stone. It is more dense than most stones.
Melon #8000 - Very Fine
The Melon #8000 is a very nice polishing stone. Shapton spent thousands of hours on research and development on this stone to make it perform up to their standard. It will leave a very fine polish with a microscopically fine scratch pattern.
Yellow #12000 - Extra Fine
The Yellow #12000 was originally designed for fine woodworking tools requiring an extremely fine edge. It will leave a bright mirror finish. It is a serious polishing stone.
