Thanked: 121Crumbling edge
Still making a lot of mistakes. I know I'm screwing up here, but could someone tell me how?...
Subject is a fairly new Bismarck. Could not get it above mediocre with several aggressive, then consrvative pyramids. Under 60X there were maybe a dozen chips along the heel third of the blade, so I decided to reset the bevel by doing circles on a Norton 1K.
Took maybe 150 to get the dings out. TPT felt sharp, but would not cut arm hair or do a HHT anywhere along the edge. So I did maybe 50 more, then looked through the scope. Then I noticed, along the middle part of the blade (away from theoriginal area of concern), that the edge appeared to be crumbling. To the left and right of the crumbling area, I could see a very thin line just off the very edge and parallel to it.I did a few more circles then scoped it, and that area had also crumbled away.
I did use some pressure when doing the circles. I think this was my mistake. I don't suspect overhoning because, as I understand it, doing circles eliminates that. I don't suspect poor/corroded steel, since the blade is only a couple of months old and it is a Dovo. I've read that grit from lapping (I used wet/dry sandpaper up to 420) can get caught in the Norton and do this, and I did lap the thing just before honing.
My thought is to use a soft brush and some shave soap to clean the 1K surface, then go back to circles on it, but this time with no pressure (other than the blade). Is this what you would do? If not, what? Do you agree that either a gritty stone or my hand pressure (I'd guess equal to several times the weight of the blade) was the problem, and -- whichever it was -- this could be the fix?
Many thanks.
