Clay tempering is perhaps one of the most skilled artforms of sword making. The process starts as if an artist is composing a painting. The swordsmith paints a clay mixture onto the rough, shaped blade, carefully applying different thicknesses of clay to both the spine and cutting edge. Finally, he adds his own personal markings onto the blade with a thin metal tool, a mark that will only be seen when the sword polisher reveals the soul of the sword, the unique natural temper line, or hamon.
Through rapid heating and quenching, the spine and cutting edge cool at different rates because of the clay coating, resulting in a cutting edge that is extremely hard, and a spine that is durable and flexible enough to withstand the stress of battle, providing improved shock absorption. Passed down from generations by swordsmiths, a clay tempered sword is a testament to precision, art, and ingenuity. Check out our wide range of clay tempered swords, including katanas, odachis, and tantos. Each of our blades is handcrafted with the utmost care and attention to detail. Choose between a strong and durable samurai sword or a stealthy and flexible ninja sword – it’s your choice.
