We use those blades at work also. We have some for aluminum, and some for steel. Do yours start out gold in color? Ours are gold colored, and I just wonder if it's some kind of surface coloring? Might be cool if it stayed that color I guess.

You've got me stoked to try making one now!

Our blades are silver in color. The gold on the blade is probably just a coating like on some drill bits. They make strong blades and some can be heat treated if u can find out what grade steel it is. Or u can do like I do and make a small test blade and torture test the crap out of it.

Our machine shop has an oven...maybe they have a Rockwell machine. That'd be convenient.

I have a tester and a oven at work too I'm gonna heat treat the next one this week. And see how it does. I also have a oven here at home but I have to wire up the controller and run power 220 to my shop.

Ok well I just tested the blade and it's at a 57 Rockwell, so I'm not gonna be doing any heat treating. I think this should be plenty tough enough, for any working knife. If any experienced knife makers have any input that would be great. Again the metal I'm using is a industrial saw blade that was carbide tipped. Thanks for any input.

That's right about where it should be, IMO.
