Woodworkers of all skills are turning to Japenese waterstones to keep their tool edges sharp. Not only do these stones cut very aggressively, but they come in comprehension range taking care of all your sharpening needs. All japenese waterstones are man made which means they are free of impurities and have a very consistant grit size. Only water is needed to lubricate the cutting stones. Since the stones are relatively soft, they are constantly exposing new grit with each stroke. Another benefit of the stone is the way they build up an abrasive sludge when used. This "loose" grit is what helps the stones give their excellent finish. No stropping or polishing compound is needed when using these waterstones because they polish as they hone.
