As to heat treating this, I can't even build a combustion without getting yelled at, how the hell am I supposed to make a forge?
same situation here man :evil: My mom caught me grinding away at one of her old kitchen knife's that was broken in half and all hell broke loose :roll:

That steel is shit, you won't be able to get it sharp (if you think it's sharp, you don't know sharp) and it can't be treated. Just use it as practice stock and leave the knife as a practice or display piece.

inonickname, 2 things, first off you have no idea how hard it was to spell your name without capital letters... And 2 I know what sharp is, I cut my hand open sharpening my real pocket knife. Its practically sharper than my new utility knife.

Bro I have to step in here because if you are using the proper methode you can put a straight razors fin on just about anything including wood!

Sharpness means absolutely nothing if it cant hold an edge. Also when making knives, its generally a better idea to grind the shape of the blade before even thinking about the edge. Hate to sound like that guy, but this thing is essentially a hunk of metal that you could maybe use as a pry bar.

Well, you could get close. But it would still be harder to put an edge on than a good hard steel, and it wouldn't hold the edge once you've tried cutting anything much harder than butter.

And BTW, not all materials are made equal. Obsidian can be sharpened (well, knapped) to a MUCH finer, and thus sharper edge than any steel, to the point of being atoms thick. Same goes for a good, treated steel vs. what he's using.

If you want to get an idea of what I mean, go get a chunk of hardwood and try split it. I've split through a dozen or so 12" x 5" round jarrah scraps with my bowie I made from spring steel, and the edge is still solid.

Anyway, moot point, seen as it's a display piece.

If you have heavy cutting/grinding gear in the future you could try using a leaf spring for a heavy duty knife (it will have to be curved unless you heat and beat it flat), or failing that, an old file works. Work slowly so you don't knock the hardness out of the steel and once it's done pop it in the oven at around 200 celsius (IIRC) while mums out shopping.
