Heat treating Machete steel? Possible? Worth it?

[BRad704]

I have made a couple of knives from a cheap walmart machete just to practice and learn before buying more metal, and I am curious, is it possible or worth it to try and heat treat it?

Or could I use a torch along the edge or something to give some color variation? Just curious...

Thanks,

This is the second blade I got out of that machete....

It is most likely some type of mid carbon steel which can be HT pretty easy. Heat edge with torch to non-magnetic, quench in a light oil maybe a gallon at 125f or in a brine solutions 1 lb salt with 2 gallon water. Put in oven and roast for 2 hr at 400F, done when tan color and burns finger tips.
