Nice addition to my sharpening routine. Tight fit but stretches.
Great bit of timber and in the dimensions I like to work with. Now just to find the right project to use it on 😅

Aichi Aus-10 San Mai with Damascus Stainless Steel Cladding, Made by Sanwa Special Steel company.
This steel is supplied cold rolled and annealed. It has a smooth surface free of decarburisation or pitting and is soft and easily cut, ground, drilled, and filed. Once polished etch in Hydrochloric and ferric acid to bring out the pattern.
If you dont micro texture (Hammer while cold/hot) to disrupt the pattern you will get straight layers.
