The reason for the choice...

..other than not just defaulting to O1, which I can do well (even the miscues heat treating have made good irons. I've got one that didn't get hot enough and ended up around where I'd want it after temper - so it didn't get converted all from pearlite to austenite - it's still a good iron and I never tempered it.)..

...at any rate, the forgeability of 52100 and its toughness at a good range of hardnesses without giving up strength or hardness potential, it's not expensive (that's not that important, though), and the low abrasion resistance for finishing and for sharpenability at a level of performance).

By charts, it's a bit better than O1 - does it matter? I don't know. By that, I mean it will have double or more the standardized toughness at a given hardness vs. O1, the same wear resistance, but it will feel like 1095 or similar when sharpening (but O1 is also very pleasant to sharpen around 60/61 hardness).

It's as good of a choice or edge strength as files, but with no more guessing and combing listings.

Struggling a little with the aesthetics, though - putting big crisp bevels on the chisels does make them look a little bit more modern than I'd prefer and it erases the eccentric curve look a little at the tang.

I guess more or less for the steel, it's what I wish 1095 was. A little better hardenability, better toughness, probably more stable in the quench (though anyone making A2 would probably think it's terribly behaved) and because I'm not doing much more than, shaping, temp cycling and quench and temper, I'm not running into the myriad of issues knife guys talk about troubling with (it can crack easily if forged heavily outside of its range, and have issues with things like carbide coarsening, though it's a very fine grained steel and I can't see that being that big of a problem).

Thanks for the nice comments, by the way. It's all just a journey of screwing around. If it never would even get to usable tools, I'd be frustrated, but it's no big deal. There are just a couple of little things that make it really attainable without much tooling and some of the specialty stuff I've bought (a larger stainless two burner forge), I'm not using - it's not needed. The high speed ceramic belt and a contact wheel is just really wonderful, though - like what a good shop knife is for a woodworker.

These are steve V's chisels, and he will put crackingly wonderful handles on them - I think the aesthetics are just not quite up to it, but ..we'll see. Maybe his handles will bail them out a little.
