Thread: Lapping scratches...

In theory if a hone were perfectly flat no matter what the grit it would not cut, just as you could make a saw out of the hardest steel in the world and without teeth it would be useless. The scratches will be a problem if it forms a repetitive frequency- where the peaks line up and the valleys line up, which will sawtooth your razor. If they are random circular scratches you'll be fine. The hone has literally millions of scratches and textures and what not at the micro level. Thats what makes it work.

I think the concern is that scratches that are large enough to see indicate peaks and valleys that are larger than normal and which might catch the blade and cause micro chipping. Or at least that is my concern.

Yes, that's it exactly.

Ah I see. yeah then you'll have to take em out with a finer grit progression. If you go to an autostore, they sell a multipack of 3m wet dry that goes like 200 400 600 800 1000. Worked well on my Swaty after I blasted it on the 120 grit.

That's why you need two Swaty's; so you can remove the scratches ;-p
