Thread: When to stop on 1k stone

For me (and your tests may vary) I test 4k at skin level and it should feel more crisp when it cuts arm hair, for 8k it should start to tree top arm hairs and just touching arm hair at skin level it will fall over. I also check often with magnification, 8k will leave an almost mirror finish

For passes, I do sets of 20 and recheck
