On this one I rounded the end of the tang and tapped it for a 8x32 fitting.Looking good, thanks for the progress photos. Did you weld the screw onto the tang?
Yep. This. The purple color is only when it’s wet.Re: stag coloring. Much of the sambar is treated with potassium permanganate prior to cutting and shipping to control bacteria formation. It is a deep purple color and a strong oxidizer. That combo imparts a really deep color on the stag.
Its typical use is in water treatment.
I use a refectory mixture. I’ve had it several years so it’s about time to try something new. I clean the blade good and coat the spine and blade in a semblance of a pattern and let it dry before putting into heat treat.That's coming along quite nice.
What method did you use to create the hamon?
