As some of you may know, I recently did a differential heat treat on a 1095 blade...and I could see the hamon after hitting it with some emery cloth...so it was there....
Now I can't see it.I left an almost unreasonable amount of meat to grind off (I thought it was around .05 but a jig malfunction just made it look that way...it was closer to .075) I took it home (I heat treat at work) and finished the flat grind to 400 grit and can't see any traces of a hamon now. I did run a file down it and it cut to roughly where the hamon line would be and then skated so that's giving me hope.
I suppose what I'm asking is , can a hamon be ground out? My metallurgical instincts tell me no due to the nature of such a beast but this may fall under the vast category of things I don't understand.
....or maybe I just worry too much and it'll be there after I etch it....
