Here’s a better picture of the forge, after we turned it off.

I didn’t get any pictures of me heating the blade, or quenching. The forge was HOT! It only took about 30 seconds for the blades to get bright orange. Then I quickly quenched them in the peanut oil, putting them in straight vertically, and dunking them a few times before swirling it around. I then put the blade in the preheated toaster oven for tempering.

Mike was a little worried that we over-quenched the first blade. I’m curious what the experts think about this. I left the first blade in the oil for almost a minute.

Mike set the timer on the oven, and we went to get a beer and some lunch around the corner. Making your own tools is great! So relaxing. We got back a little over an hour later. The blades were still hot, but handle-able. I cleaned off the oil and took a look.

Not bad. Back at home I went back to the WorkSharp to regrind the edge and flatten the back.

So there you have it. Provided you have access to a forge, total time to go from a shaped untreated blade to a hardened, honed cutter is 90 minutes. And that includes fabricating an oil container and a leisurely lunch with beer.
