Well, I finished up a kiridashi I made for my Dad for father's day this weekend. 1080 Steel 1/8" stock. I hope it performs. The steel got a little darker than I wanted while tempering. My oven sucks. It's very inconsistent, even using a pan of sand to try to keep things even. Dad will definitely put this thing through it's paces so we'll see how it holds up. In it's current state, it's pretty darned sharp. Just hope it holds the edge. The good thing is that it should be easy to keep sharp.

Don't worry about the color of an oven tempered blade. Those colors don't mean anything. Temper color charts are for flame drawing a temper.

Most people temper too low anyway. They think a few degrees make the blade much softer. Truth is, for most balde steels, 50 degrees barely makes a change in hardness you can't really tell without a rockwell hardness tester.

Getting the quench right makes far more difference.

That's good to know. For now, I'll trust time and temp. Just scored a toaster oven at Goodwill for 12 bucks that holds temp on the dot. Checked it with an oven thermometer that I know is accurate. Little by little...
 
Looks good!

I keep a kiridashi on my bench for cutting leather and I love it.
 
Kiridashi and Kwaiken are much under appreciated knives.

The biggest difference between the two is a kiridashi does not need a handle or sheath, and a kwaiken has a handle and sheath so it can be carried in a pocket. The kwaiken was traditionally carried in the kimono sleeve pocket or lapel pocket. It performed the same tasks as the Western world's EDC folder does.
