Industrial dagger.

I actually like that a lot... it's just cool. And the contrast between the gnarly rebar surface and the hand finished bevels...
Was the rebar hardenable?

Nice. I made tongs out of re-bar once and quenched in water to cool it and couldn't drill the pivot hole. Seemed to harden quite a bit - good enough for a dagger I'd suspect.

Thermally reinforcement rebar - enough for dagger.

The first thing I've ever seen made of rebar that I like, and I love it!!!
Congratulations you've done the imposable in my book.

that's super neat. I'd call it an Artwork for sure, it definitely has something to say...

Back when I was just starting, I made an anvil hold-down tool out of some #6 rebar... quenched it to cool it down quick, as you would with mild steel. I went to use it (tap it into the pritchel hole) and the sucker snapped clean. That's how I found out some rebar will harden... some also won't, some bars have hardenable spots and mild spots. You can buy grades of "weldable" rebar specifically if you need low carbon throughout, as we did in the floating dock industry.
I've seen people make quite usable junkyard type knives out of rebar.

Nice job! I bet that it will be all it was intended to be. With a little tweeking, that rebar will stab with the best of them. Talk about a never ending supply of material.

I like that. Very interesting and unusual.
