This is a small finishing stone from Imanishis stone company. The stone weighs 620g and is a good stone to try for those of you that have interest in Japanese natural stones without investing a large amount in a larger stone. These are popular stones for use with kitchen knives and razors. Measures 140mmx78mm 25mm.

I've used this stone several times and it seems to be about 7-10 K in grit but that's a guess. It's a splash and go stone like most naturals and it leaves a nice finish for kitchen knives. The nice thing about naturals in general is they cut and polish at the same time so you can start with a mid range stone and just jump up and use this one and it works great.

Very good stone. Not very hard but decent cutting.

This is a great stone. A bit gummy in feel but once soaked it works a decent mud.

I would say it is 6000 grit equivalent, great for stepping up to 8000 grit.

Bought this for woodworking. Been collecting a bunch of J-Nats and this is my first review. I used this to polish a bevel on a western carbon steel chisel in a honing jig. Although it is small in size I had no problems using it with the jig. The stone has a nice smooth feel to it. Its a little soft for a natural. I didn't work up a mud base but just polished lightly. This left a polished matte finish with very fine scratch pattern. I'd imagine it would get finer if you built up some mud, but tends to dish the stone so I don't do it. The size and cost is small but it is a very fine stone. It is not as fine as the Ozuku however.

Best small finish stone on the market. If you are shopping just stop and buy it! It is a finish stone so good that it will finish a razor or kitchen knife with great results. I have tried it on both.

Impressive stone. Puts an Edge on a blade really quick, as it is a splash-n-go (just add water & sharpen - no soaking required). I however do not sharpen razors so I can't say if it is good for sharpening razors but it is great for high carbon blades, however it is not very large, but what a bargin for a natural stone $50 (that's a steal).

I have been using this stone alot and really like it. It leaves a great edge. The edge it leaves is kinda matte and I would estimate it to be around 7k. Excellent value for the money.

After using this for a couple weeks I'd have to say I'm pretty impressed. This is my first Japanese natural, so I didn't know what to expect. On the couple of VG-10 knives I've done with it the results were nice although not amazing. However, the edge it puts on carbon is pretty sick! For such an inexpensive stone I was pretty impressed with how sharp it got my Hiro AS.

Again, it's hard to rate this one since I don't have a good frame of reference. The performance on carbon is fantastic, and the price was great. So this probably isn't a Five Star stone in it's own right but given the price I think it's warranted.

First natural and not the last. Great small stone for those who wish to try out a natural minus the cost. Does take a little longer to get mud going but leaves a nice 8-10k finish. And as always great service from Mark.

This is an interesting stone for it's range. It's softer than most but very fine. I used it with 3 razors and feel it's in the 8-10k range for polishing. A great step up to the higher finishing stones. Can be used to shave off of but does better as a step up.
