SRS13 is a unique powder metallurgy martensitic stainless steel enriched with molybdenum, vanadium, and tungsten that is the steel of choice for many premium-grade Japanese kitchen knives. SUS405 is a ferritic stainless steel that provides greater overall blade strength and toughness while allowing the hard SRS13 core to excel at cutting performance.
