San Mai steel bars are William Engineering’s highest quality steel offering. These high-end cuts of steel undergo a unique bonding process before they are considered San Mai. Here on our site, we offer San Mai steel bars that allow knife makers and steelworking enthusiasts to make their own knives. These San Mai bars can be forged and machined into any shape our customers desire. A unique pattern is revealed when hot forged. For material removers who don’t hot forge, the pattern is more like that of a wood grain. Either way there is a stunning contrast revealed in the materials after etching. Check out our San Mai steel bars to find the right starter for your knife, today.
