I've used oilstones, waterstones, Arkansas stones, diamond stones, India stones, etc throughout my life, but the Shapton stones outshine them all. They're ceramic with even, precisely controlled grits. When sharpening, I can see the steel coming off the knife and hear as well as see if my angle is correct. They cut fast and are an immense pleasure to use. I took to them immediately because it was a wholly new sharpening experience for me.

Excelente piedra para dar el primer pulido al filo muy agresiva.

All of Shapton's products - the glass stones, the pro/ Kuromaku line and the accessories are excellent products you can purchase without any doubts. This stone is a bit of curiosity - it lies right between sharpening (800-3000Grit) and polishing stones(5000+). As such this product is somewhat unnecessary for most people, including myself. A particular Japanese knife of mine really shines at the 4000Grit. If you're going for a single stone purchase look at the 2000 gritstone from Shapton. For multiple stones you can't go wrong with a 1000 and 6000 combination.

Excellent but expensive

Could use this stone for final polishing if so intended.Good mirror edge if you know how. I think many people's normal usage would suffice with this stone!
