Long-Life Rubber-CushionedAbrasive Grinding Bits for Metals. A diamond abrasive that's bonded to a rubber cushioning makes these bits last 10 to 20 times longer than rubber-cushioned bits without diamond. Because they're cushioned during grinding, these bits produce a smoother surface texture than other bits with similar grits.

In general, sharpening is more effective when you match the size of your stone to the size of the blade you are sharpening. Small pocket knives can be sharpened on 3" stones and large kitchen knives are best sharpened on 11-1/2" stones. For the best results, choose a size that allows you to sweep the entire length of the blade across the ...
