It'll look the same...

..it was very hard, but held up fine. It may lose corners easily in heavy work. Chopping maple is resistant compared to most of what we work, but all of the strikes are straight in without much wobble. Where I get in trouble with nice japanese chisels is slipping them in a plane mortise or something like that where they're being worked and turned at the same time out of laziness. Whatever a japanese chisel will do, at 325-350F, these chisels will also do.

AKS (the vendor) provides a curve with parks (which is what I use) and of all of the steels where you can hit the targets in a garage, a steel like this is one (no real need for normalizing, very simple, and gains full hardness right past loss of magnetism, so no guessing like with some other steels that like to be quenched a top hardness another 150-200F plast magnetic (I overshoot on those on purpose as it's better than undershooting).

At 350F, these should be 63/64 (at 380F where they are now, I would guess 62, but the lack of anything other than a tiny amount of chromium makes them feel like there's absolutely nothing abrasion resistant in them. They're dreamy to grind, very "dry" and at high hardness they drop their burr even on a washita without having to do anything.

As tempered in this picture, they're not quite as brisk on the washita, but one quick stroke back and front and 99% of the burr is gone. The buffer puts the uni stripe on the chisels very quickly, too, since there's nothing wear resistant in them. Thus the comment that they would probably make a wonderful plane iron, but one that wears like old water hardening steel.
