Naniwa Super Stones

These are among the most popular composite whetstones made, and an excellent value in a high quality Japanese-made stone. They are resin-impregnated so they are very fine and smooth and do NOT require soaking -- just spray/wet and you're good to go. Very easy and forgiving sharpening, and long-lasting. These stones are great for the pro or serious home use, as they do not have bases and are a full 2cm thick, so they'll last for a long time!
