Naniwa Super Stone extra coarse 220 Grit Japanese Whetstone Sharpening Stone, NO Stand, 21cm x 7cm surface, 2cm thick.
This super coarse stone is perfect for very quickly grinding a new edge on your knife, and for working out nicks or cracks or other imperfections in old used/abused/damaged knives. Use this grade only when you regular maintenance and finishing isn't doing the trick anymore. It's very coarse and so will cut (remove metal) quite aggressively, so use care. It is the coarsest New Super Stone Naniwa makes!
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 SuperStone series at home and they're great.
Note: these are now branded "Super Stones" again and now come in a grey box that says "Super Stone"... in 2015 Naniwa re-branded them "Sharpening Stones" for the North American market, but I think they finally realized that didn't make sense so they're gone back to the better-known "Super Stone" name.
These are excellent stones! High quality, long-lasting, great value, not fragile.
NOTE: This is a full 2cm thick stone! We do NOT and have never imported or sold the cheaper 1cm thick versions of these stones.
Warranty: One-year warranty against manufacturing defects.
