Grit-confused

[pompon44]

Hi,

I was wondering how the grit number of waterstone relate to sandpaper grit and to carborundum grit ? For instance, lapping the back of a blade with a steel plate and carborundum grit up to 400, what's the equivalent in "stone grit" ?

Sorry for the dumb question :?

Regards,

Not a dumb question--you'll have to try harder for one of those :lol:

Ok, thanks.

So if I read correctly that chart, if I go to my 1000 waterstone after steel lapping up to 400, I'm not going backward, am I ?

Regards,
