Thread: prep for frist use for The Natural Finishing Stone - 12,000 Grit is quarried in China

I bought the Natural Finishing Stone - 12,000 Grit is quarried in China, do i need to lap it first? it seems like it has a lot of scratches and stuff in it.

O yes you do draw a pencil grid on the stone and lap it with a dmt or sand paper

a pic of the stone would be nice !

I'll get a pic, but i have two other questions that go with this: 1) i have the 4000/8000 norton and does that need lapping right out of the box and 2) if you use a courser grit than the stone, does that make the stone more course? I've read that using 400 grit paper and a glass plate is the way to go or is the lapping stone better?

and what is DMT?

yes what that guy said ^

so, I've been working on my honing skills and getting less than stellar results and it could have been b/c i didnt lap them right out of the box? I'd have thought this was done at the factory. They're new.

no its not the norton look like a cinder block when you get then once you lapp then you'll be amazed of how much smoother they get

When lapping a hone, either a Norton or a Chinese 12K, both of them should feel smooth in order for them to be lapped good. When I lap my hones for the first time, I feel the different parts of the hone as I am lapping. If I feel a little rough patch, I go back and lap it until it is smooth. Your less than stellar results could be from a hone that needs more lapping, or it could be from honing too little.

and since your new at hone i would tape the spine on the razor so you dont destory it with spine ware

A Norton isn't even usable when new an unlapped, it certainly needs it.
