I'm stuck. Where to get heat treated?

Well, I'm working on my most ambitious knife to date. A D-guard fighting knife. I've got 99% of the metal work done. A little file work and polishing is all thats left. But since I'm putting this much effort into this knife, I thought I'd get it professionally heat treated, instead of my usual, "heat it till its red and dunk it in ice water" approach.

And yes, I like the rough look.

So, does anybody know a good place I can get my knife heat treated? I live in Southern Indiana if that helps. Its also 4067 steel I think. Definately 40** something at least.

I may be wrong about this....but it might be hard for someone to professionally heat treat it properly if you are not 100% on the steel type yourself....40** something is not really specific. You might end up doing just as good a job heat treating it yourself...but I would not suggest using ice-water to quench.:eek::D

Well, the label on the piece I used said 4067, but I'm unsure about how much I can trust it. In my copy of "Machinery's Handbook", there's nothing on 4067, which is where my confusion comes from.
 
I'm not sure this steel is going to harden to any degree. Maybe in the 40s, if you're lucky. Just wondering why you used this unknown steel, and spent so much time on it?

Well, according to my sources, it is definately hardenable. 4063 is used for coil springs, 4023 for differential gears, and we all know how tough those are. I just lack anything specific on 4067 is all.

As for why use this metal, I've used it before for knives, and they've all been pretty good about holding an edge. I just don't want to screw this one up since I've spent so much effort on it.
 
well it would be cool to play around with if you had a HT oven and a rockwell tester but I'm not sure anyone used to heat treating knives will know what to do with this.
 
I heard back from Brad Stallsmith and he says he can do it and keep the hardness in the upper 50s RC (Rockwell).

I actually might have access to a Rockwell Digital Hardness tester. I just need to get in contact with one of my old college professors. I'm sure he'd let me bring in a few "home heat treated" samples for his students to test.
