I didn't check with a metallurgist..

..but I believe manganese isn't added for toughness, just for hardenability because none of the manganese only steels (like 1095 and white 1) have any decent toughness in notch tests, but 52100, which is similar but with the chromium addition is monstrously tough.

I think a google search would find that to be the case, otherwise what I'm seeing is unexplainable. 52100 has drastic toughness compared to the other plain steels I've forged, almost circus-like. When planing, I noticed none of this, because the edge was never challenged. It makes a beautiful planing iron, just like ideally hardened O1 does. It doesn't wear like XHP, but it does wear about like O1.

In doing these bits of testing, though, it's the relative comparison of tools one after another that's valuable - if you use them in isolation, you can't see how stark the contrast is and if you're making them (like I am), then it's really worth chasing to get something that "just cuts and cuts and then refreshes easily.

I'll clean up the 26c3 edge and compare it to the ward. I'm hopeful that it can come close to matching the latter (which is as good as any chisel I've ever used, even though mine's a little later and not as neatly made). 52100 isn't going to have a chance in feel and effort without leaving it much harder. really ideal O1 might.
