Naniwa Super-Stone Japanese Whetstone Sharpening Stone, 12,000 grit

16 items left

Naniwa Super Stone 12,000 Grit Japanese Whetstone Sharpening Stone, NO Stand, 21cm x 7cm surface, 2cm thick.

A very popular stone with people sharpening razors!

This ultra-fine stone is used for giving a knife (or razor) a final polished edge. There are manufacturers which claim higher grits, but few can yield a mirror polish edge like this Naniwa Super Stone 12k can. Recommended for final finish of fine Japanese stainless or carbon steel knives. Not necessarily recommended or needed for most German knives (though you could try with a fine slicer I suppose, I wouldn't really recommend this kind of edge for a German santoku or chef's knife since they generally hold up better with a slightly rougher and thicker final edge).

These are excellent stones, very reliable, forgiving, and not fragile. A GREAT choice for the beginner or casual home user who just wants good long-lasting stones that work great on a variety of knives. I use these Super Stone series at home and they're great.

Note: Naniwa has re-branded these (again) as "Naniwa Advance" for 2024. The stones are identical, just the branding/name and packaging has changed (again). You may receive the new or old packing as we receive and make the transition to new stock from the factory in Japan.

NOTE: This is a full 2cm thick stone (code S2-491). It has been brought to our attention that other vendors are importing the cheaper 1cm thick version (S1-491) and then not always specifying the thickness on their web sites. Those stones are cheaper, and being half as thick will be more prone to breaking and will not last nearly as long as these normal full-thickness stones! We do NOT and have never imported or sold those cheaper 1cm thick versions of these stones.

Warranty: One-year warranty against manufacturing defects.

Great stone for straight razor. Easy to use and produces excellent results. Plus, a good price for such a large/thick stone.

Ultimate!!!

A perfect feel when sharpening the straight razors I made, and customers razors also.
I gives them an incredible edge, I will soon be purchasing more stones maybe 16000, or 20000

Nice mirror

It's a nice stone that leaves a near perfect mirror finish. Seems to be very hard, perfect final stone for straight razors
