Katana Blade Types
Clay tempering gives a sword blade both flexibility and hardness, and clay tempered katana exhibits excellent durability that is inherited from high carbon steel
Folded steel blades, usually referred to as Damascus steel, are made by hammering the steel flat and folding it over repeatedly to create multiple layers of steel
Carbon steel is durable, extremely strong and shock resistant. It is one of the best blade materials, and can be easily forged, maintained and cleaned.
