After thinking about it, I suppose it would have been nice if a description was added.

This little skinner/bushcraft knife I came up with is made from 5/32", 1095, it is my first attempt at heat treating after exhaustive research on it.

I heated it in a charcoal forge to non-magnetic and brine quenched it (no pings). I gave it 3, 1 hour cycles at 360 for tempering.

It has a single bevel and took a razor edge, which after cutting packing tape, summer sausage and cheese, is still popping hair with no touch up, might I have had some beginners luck?

Alright, well, I don't have much in the way of critique, just a couple of notes:

Because you did a brine quench, which runs a high risk of cracking and warping, I would probably avoid it for blades with only a single bevel because the uneven geometry will want to warp. Looks like there might be a little nick/hickup in the exposed tang leading out from the handle into the blade that could have also potentially gone awry in the quench - the future make sure your profile is smooth before any heat treat.

Did you do any normalizing before quenching?

No, I was working with annealed steel and it was stock removal done mostly with files so there was very little heat generated, I also noted the little imperfections in the profile you noted, I should have noted it pre-heat treat, but I was rushing to get it done so I could start testing the design and the heat treatment, could of blown the hole test.

Interesting thought on the single bevel, I did not realize that it would cause problems as I left the edge a little thicker than a dime.

Hope he likes it.

 

It is oil quenched 1095

Japanese grind front and back.

Gun blued above the blade road.

Thank you!

That was intentional, I had seen that done on several examples of traditional Deba knives, I also refined the handle as I found it a bit clunky and finished honing it. It took a razors edge and my son loves it.

 

P.S. the best new is I finally figured out how to properly post pictures!

Annealed 1095, worked with files and sand paper, so no normalizing needed

Brought to non-mag, quenched in olive oil at 130f, 2 cycles of 1 hour at 360f.

No visible defects in the blade.

You are correct, the test will be how it performs over time.
