What is San Mai steel?

San-Mai, or sanmai (“three layers” in Japanese), consists of a central core made of very hard, sharp steel, with a layer of softer steel on each side of the blade to absorb shocks and extend the knife’s lifespan. These blades are more durable than single-layer steel and less expensive than more elaborate Damascus steel.
