VG-10 steel was developed by Takefu Special Steel Co. Ltd. It has a high chromium content (15%) and cobalt (1.5%) making for a wear resistant stainless steel.

It is probably the most popular stainless for factory made Japanese knives and can vary greatly in quality based on forging and heat treatments. Not our favorite steel to sharpen because of the Cobalt content, but will have good edge life and is low maintenance.
