Wow,
I'm still having problems with this stone. I emailed norton originally through their website, and never received a reply. Does anyone have their phone number?
I've honed some razors, and they have turned out decent. lapped between each, and today, after I lapped again, the grit and roughness is back.
I've also since bought a norton 220/1000 and being a lower grit, is still smoother than the 4000 side of my 4k/8k.
any ideas?
