You are looking at a high quality fully functional Japanese Sekinetsu Katana samurai sword. The blade has a Maru Lamination . It is made from T10 tool steel and has been differential clay hardened. This high quality full tang double pegged katana exhibits one of the most appealing Hamon temper lines that is authentic and distinct as a result of the differential hardening process. And the hamon has been further enchanced by the traditional polishing stage “Hadori Polish”.
How important is differential hardening?
A differentially hardened katana (as opposed case hardened or tempered) features a softer spine and harder edge. The blade edge is hardened in order for it to retain it’s sharpness overtime, Keeping the spine softer helps the sword to bend and not break.
Making a differentially hardened blade is being done performing coating the blade with a layer of clay, each swordmaker has his own secret formula.
Differential hardening is key to making a battle ready katana that will be used for extensive tameshigiri (test cutting). Our expectation is that a shinken should survive at least 10,000 tatami omote cuts (10 years of heavy use) and only need minor sharpening after every 500 (six months of heavy use).
High End Finish
When the rough blade is completed, the sword smith turns the blade over to a polisher called a togishi, whose job it is to refine the shape of a blade and improve its aesthetic value. The entire process takes considerable time, in some cases easily up to several weeks. Early polishers used three types of stone, whereas a modern polisher generally uses seven. The modern high level of polish was not normally done before around 1600, since greater emphasis was placed on function over form. The polishing process almost always takes longer than even crafting, and a good polish can greatly improve the beauty of a blade, while a bad one can ruin the best of blades. More importantly, inexperienced polishers can permanently ruin a blade by badly disrupting its geometry or wearing down too much steel, both of which effectively destroy the sword’s monetary, historic, artistic, and functional value.
On high quality blades, only the back of the blade and the adjacent sides, (called the shinogi-ji), are polished to a mirror-like surface. To bring out the grain and hamon, the center portion of the blade, (called the hira), and the edge, (the ha), are usually given a matte finish. Microscopic scratches in the surface vary, depending on hardness. Smaller but more numerous scratches in the harder areas reflect light differently than the deeper, longer scratches in the softer areas. The harder metal appears more matte than the softer, and the manner in which it scatters light is less affected by the direction of the lighting.
What is Hadori Polish and why?
It is an optional stage of traditional Japanese sword polishing, whereby the Hamon is enhanced by polishing with a coarser abrasive than the body of the blade, leaving it whiter in appearance. The hadori style is named after the hadori stone used, a waterstone selected for its slightly greater coarseness which helps lighten the hamon and make it stand out against surrounding areas. The hadori style cannot exactly replicate the hamon as the finishing is actually a trace of the original; thus its quality depends mainly on the nature of the hamon itself, available equipment and the skill of the polisher. The goal of hadori polish is to bring up the aesthetic value of the sword.
The balance of the blade is perfect and the sword is completely functional. It can be used for Tamashigiri (target cutting).
