More uradashi or hammering theory

Small pock marks work for more control over the bending of the metal, as opposed to deeper chisel type marks. A deeper mark isn't necessary more effective than a lot of shallower marks. Carbide hammers are helpful to bend the hard steel in the front, to correct microbevels on the ura side of single bevel knives. Hammer where the microbevel would be on the other side, to move such that it just becomes part of a normal more planar ura. Check occasionally by sharpening the back. Very easy to chip... So light taps, and extremely light test taps to sense where to hit and not to hit..

When I tried to correct a microbevel by hammering the iron, it wasn't close enough to the microbevel to bend steel there -- it would just make the whole ura deeper, apexed where the hammer marks were made.

It is possible to bend steel without carbide, like with edge deformation.... Just less controlled
Addendum to hard steel

Some steels are chippy and have coarser grain or are very hard. They don't respond well to uradashi of hard steel and crack and chip lol

If steel chips easily or has a chipped tip... Yeah, it'll break

But most steel will bend

Also, just because it's a deba doesn't mean the steel will be softer or tougher . . .

Stamps on the blade, or stickers, don't necessarily mean it's much better. . . Just some things I've read on blades. Even buffalo horn doesn't necessarily correlate with quality.

The best ones have been where it's just a nice chiseled engraving, or stamps with deep kurouchi. Good sharpening too. . .

Yeah that's helpful, I've seen shobu translation before too, but just wrote whatever Google translate had. Still needing to memorize the kun and on readings of kanji, and kanji in general.
