Hello Friends,

Newbie here...
(As if you couldn't tell)

I recently got a set of stones which have no markings and some are double-sided (coarse/fine) and some one grit in different levels of coarseness.

Is there a way to test/measure the grit?

I know one company's measure may be differeent from another, btu is there any way to determine before sacrificing any razors?

Thanks for patience and comments!
Joe.
