Damascus steel made from rasp blades on plasterboard.

The blade is made of drywall blades and powder steel. I don’t know the chemical composition of these blades, but a large diffusion of carbon from the blades into the powder steel occurred. And the blade as a whole received a very high hardness during hardening, it was necessary to temper it at a temperature of 280 degrees Celsius to reduce the hardness to 58 units. In addition, it was not possible to etch the pattern beautifully, since both steels had approximately the same etching rate. Thank you all for your support in the comments.
