okay just tried honing for the first time with my new Norton 4/8 grit stone. ummm i think i was doing well, well the reason i was honing was that there was a small nick in the blade(nothing big, just that i wanted to get rid of it). Any way i was making progress and i looked at the stone and there was like dirt or something on the stone, is this normal? I know its probably a easy answer but i want to be sure
