The Inferuno Series 7" Santoku Knife is a modern take on the Japanese all-purpose knife known as the “knife of three virtues” — slicing, dicing, and chopping. Hand-forged with an AUS-10 cutting core and clad in 73 layers of Damascus steel, this Santoku combines traditional craftsmanship with modern engineering. A razor-sharp 9–12° double-bevel edge, thin grind, and ergonomic resin & maple handle deliver precise, effortless cuts for vegetables, fish, and meat. Perfectly balanced at the bolster, it’s designed to make every prep session smoother and more enjoyable.
