Through Tempered Katana

Tempered to an Optimal Hardness and Resilience

These blades are not forged traditionally but are forged just as tough. Unlike differential tempered katana these blades are tempered to an optimal hardness all the way through the spine to the cutting edge. Many are forged with modern "super steels" and "tool steels" that lack the impurities of the traditional sand irons creating true swords worthy of the Japanese samurai. The knowledge acquired by modern sword smiths merged with the smelting ability of today's refineries give us a few hundred years advantage over the swordsman that inspired us. Taking advantage of everything learned from the past with modern technology enables us to produce even stronger and resilient swords for today's martial artist.

What is a Through-Tempered Katana?

A through-tempered katana is a sword that has undergone a heat treatment process in which the entire blade is heated to a uniform temperature and then quenched in a medium such as oil, water, or air. This creates a blade that is consistent in its hardness throughout, as opposed to a differentially clay tempered blade, which has a harder edge and a softer spine. The through-tempering process is a modern technique that was developed as an alternative to the traditional clay-tempering method.

How is a Through-Tempered Katana Different from a Differentially-Tempered Katana?

The main difference between a through-tempered katana and a differentially-tempered katana is the consistency of the blade's hardness. In a differentially clay tempered sword, the edge is harder than the spine, which allows for a sharp edge that can cut through tougher materials, while the spine remains flexible to prevent the blade from breaking. In contrast, a through-tempered blade has a consistent hardness throughout the blade, which makes it more resilient and less prone to chipping or breaking.

Benefits of a Through-Tempered Katana

One of the main benefits of a through-tempered katana is its strength and durability. A through-tempered blade is less likely to chip or break under stress, making it an excellent choice for martial artists who use their swords for cutting exercises. The consistent hardness of the blade also allows for more precise control, as the blade will not flex or bend as much as a differentially-tempered blade.
