These are superfine grits, the stones are used to bring the metal to an absolute mirror finish, and hence an ultra sharp edge. Whereas the coarser stones can be stored in water, these fine stones are harder and not so porous, so only need to be sprinkled with water just before use, and left dry at all other times. They are mounted on bases and the very finest are supplied with a Nagura stone; used to de-glaze, true and build up slurry on the surface of the stone, which helps the polishing process. The 4,000 and 6,000 grit measure approximately 190mm x 63mm x 19mm and the 10,000 grit 200mm x 75mm x 25mm. The 10 thousand grit stone is supplied with a Nagura stone. As a guide a 6,000 grit is a good choice for everyday work.

10000G stoneHaving bought the 1000/6000 grit combination stone last week (I reviewed that too), I waited until payday and purchased the 10000 grit stone. This stone is very smooth. When honing, it has a buttery feel and is very soft but still gives nice feedback with each stroke. I was very excited to try this stone and did so as soon as I got home from work. My hands were a bit shakey due to not having eaten and I put too much pressure on the blade, got the angle bad and gouged a notch out of the stone. BE GENTLE WITH THIS STONE! I managed to invent some new swear-words, spent half an hour with some wet-and-dry paper and a glass plate and re-lapped the stone.

USE THESE AND SHARP HAS A NEW MEANINGIf you have used the coarse stones to obtain a smooth finish, move on to these to provide a mirror finish with an edge so sharp it makes certain disposable razor adverts bordering on the fraudulent !!!
