SHIRASAYA:
      A shirasaya is a plain wooden Japanese sword consisting of a saya (scabbard) and tsuka (hilt), traditionally made of nurizaya wood and used when a blade was not expected to see use for some time and needed to be stored. They were externally featureless save for the needed mekugi-ana to secure the nakago (tang), though sometimes sayagaki (blade information) was also present. The need for specialized storage is because prolonged koshirae mounting harmed the blade, owing to factors such as the lacquered wood retaining moisture and encouraging corrosion.

Manual grinding:

 Using the unique bright stone of Longquan Town, hand grinding, very test sword casting skills and technology, grinding out the pattern effect is special texture!

 
Ancient quenching:
      Modern vacuum heat treatment can meet the hardness requirements of most swords, but the traditional quenching method has better effect, can soften the medium strip steel, and the hardness is higher.
 
 
Ninjato :
    The ninjatō (忍者刀) are allegedly the preferred weapon that the Shinobi of feudal Japan carried. It is portrayed by modern ninjutsu practitioners (including Masaaki Hatsumi and Stephen K. Hayes) as the weapon of the ninja, and is prominently featured in popular culture. The ninjatō is typically depicted as being a short sword, often portrayed as having a straight blade with a square guard. Historically, there is no physical evidence for the existence of this "katana-like short sword legendarily used by ninja" before the 20th century, though it is believed that the designs demonstrated by alleged replicas are based on the design of the wakizashi or chokutō swords.
