Review: wonderful stone!! 4.5 star - I used to sharpen my knife with 1000/6000 grit combination whetstone. It was quiet sharp but I decide to buy this stone to test whether it can get sharpener. The result is amazing. The blade seems to get shinier and sharpener. I can easily make a push-cut on paper which I often feel hard to do which a 6000 grit stone As a beginner in knife sharpening, I am also able to achieve a close to mirror edge with this natural Japanese stone. The thing I don't like about this stone is that It it is not flat, and it took me an hour to flatten it with a Norton flattening stone. There aren't any indicating number or word etching on the stone to confirm that it is a hard version of this stone. So I am not sure that whether my stone is the normal version or the hard version. Overall I am very satisfied with this whetstone.
Review: Es una replica. - He investigado, es una piedra muy buena y dura, que durará años, es especial por es que es para afilar, suelta un lodo qué ayuda mucho a pulir, pero no es auténtica tsushima pero es muy parecida, pero realmente me encantó, solamente si le deben de quitar ese nombre y ponerle réplica.

### ⭐⭐⭐⭐⭐ Not certified but good nonetheless
*by P***8 on 2 July 2020*

I have read the reviews on this stone and bought 1. I personally really like this stone. I have a wide variety of stones natural and man-made. I have 17 years of experience sharpening blades and I believe this to be a good buy. Some buyers seem to be upset because they don’t believe it is a true Japanese natural stone. While others seem to have fallen in love with it. For the money it is a good investment because it is a fine grit that is very very dense. which means it will last for years unlike less dense stones that you can clearly see the where after a year. If you’re looking for a natural stone that is certified this isn’t it but it is a good stone nonetheless.
