Cold Steel Knives Magnum tanto II San Mai
Just two ounces heavier than the Tanto, the Magnum Tanto II provides a full 30% increase in cutting power. Combine that with the visual impact of a tsuba-style (sword) guard and you have perhaps the ideal Tanto. The Magnum Tanto II features a blade made from San Mai III.
"San Mai" means "three layers", it is the term given to the traditional laminated blades used by the Japanese for swords and daggers. Laminated construction is important because it allows different grades of steel to be combined in a single blade. A simple way to think of this type of construction is to imagine a sandwich: The meat center is hard, high carbon steel and the pieces of bread on either side are the lower-carbon, tough side panels. The edge of the blade should be hard to maximize edge holding ability, but if the entire blade was hard it could be damaged during the rigors of battle. For ultimate toughness, the body of the blade must be able to withstand impact and lateral stresses. Toughness is generally associated with flexibility in steel, so that surprisingly, if an entire blade was made "tough" the edge would not be hard enough to offer superior edge holding. San Mai III® provides a superior blade with hard (higher carbon) steel in the middle for a keen, long lasting edge and tough (lower carbon) steel on the sides for flexibility.
The San Mai III lamination line marks the junction between two types of steel. This laminate is over 25% stronger than the incredibly tough AUS 8A stainless in the Tanto.
