Katana are traditionally made from a specialized Japanese steel called tamahagane, [60] which is created from a traditional smelting process that results in several, layered steels with different carbon concentrations. [61] This process helps remove impurities and even out the carbon content of the steel.
The steel used in sword production is known as tamahagane (玉鋼:たまはがね), or "jewel steel" (tama – ball or jewel, hagane – steel). Tamahagane is produced from iron sand, a source of iron ore, and mainly used to make samurai swords, such as the katana, and some tools.
Tamahagane. Tamahagane (玉鋼) is a type of steel made in the Japanese tradition. The word tama means 'precious', and the word hagane means 'steel'. [1] Tamahagane is used to make Japanese swords, daggers, knives, and other kinds of tools.
The block is then placed back in the fire. The steel can be folded transversely or longitudinally. Often both folding directions are used to produce the desired grain pattern. This process, called the shita-kitae, is repeated from 8 to as many as 16 times. After 20 foldings, there is too much diffusion in the carbon content; the steel becomes ...
kōgai (笄) – a skewer for the owner's hair-do, carried in a pocket of the scabbards of katana and wakizashi on the side opposite of the kozuka. [33] [34] kogatana (小刀) – any knife, particularly a small utility knife carried in a pocket of the scabbards of katana and wakizashi. ko-itame-hada (小板目肌) – see itame-hada. [35]
Blades whose length is next to a different classification type are described with a prefix 'O-' (for great) or 'Ko-' (for small), e.g. a Wakizashi with a length of 59 cm is called an O-wakizashi (almost a Katana) whereas a Katana of 61 cm is called a Ko-Katana (for small Katana; but note that a small accessory blade sometimes found in the ...
Stainless steel is a popular class of material for knife blades because it resists corrosion and is easy to maintain. However, it is not impervious to corrosion or rust. For a steel to be considered stainless it must have a Chromium content of at least 10.5%. [24] 154CM / ATS-34 steels. These two steels are practically identical in composition ...
On the other hand, the exposed edge cools very rapidly, changing into a phase called martensite, which is nearly as hard and brittle as glass. The hamon outlines the transition between the region of harder martensitic steel at the blade's edge and the softer pearlitic steel at the center and back of the sword. This difference in hardness is the ...
