The higonokami is made of mokume gane and blue paper steel for the blade.
Here I used the remnant of an asymmetrically layered block of 16 layers. We manufacture such bars with 150 x 150mm. Since some workpieces go out. This is the reason why the bar welding does not appear in the video.
For etching I use nitric acid and for coloring this patina here: mokume-gane-shop.at/collectio...
