Thread: Dan says his Arkansas black surgical stones

are guaranteed to be flat how can I tell if they are flat and how would you flatten one if you decide they are not flat?

get a flat metal piece like a metal ruler or mesuring instrument...put it on the stone and hold it at light source...if light gets in...it's not flat.
also you canwet it a bit and put it on a flat glass surface...see if it sticks...

the only way to flaten an ark is to use a flat diamond lapping plate or a flat hard substrate like a granit plate with added grit...sandpaper usualy is slow on flatening hard arks.

I have four Dan's Whetstones, True Hard, Black, Translucent. I personally have seen their lapping machines. I've witnessed their quality control processes. You shouldn't have any problems with flatness.

I don't think this belongs in here in safety razors?.....Aside, it is elsewhere?

FYI, this thread was duplicated, so I deleted the one that only had one reply.

Otay...So we are honing DE blades on Black Arks! Really flat ones!
