Antique framing square

Anybody know the type of steel used in very old framing squares? The one I have belonged to my dad, it probably came from my great uncle. Thinking it would make a neat looking filet knife.

i cannot imagine the steel would be useful for a knife. it would not need to be hardened to be a framing square, in fact the distortions from the hardening process would make it worse for a framing square.

it is always a nice thought to recycle old tools that are past their sellby dates... there are pitfalls, like unknown steels, casehardening, carbide tipped saws... but it can be rewarding, i am not fond of the unknowns in the heat treat process, but i worry too much about those things
