Things You Need to Know About Authentic Katanas Sold on the Market


A katana is a type of sword that Japan has been famous for. Authentic katanas have been used throughout Japan’s history as their primary weapon. One of the things you can look for in authentic katanas is the hamon line.

The hamon line is seen as a badge of authenticity. It is also seen as the sharpest section of the blade due to the differential hardening process the steel goes through.

A real hamon line looks white and cloudy. It looks like waves of white across the bottom or sharp part of the blade. When viewed at an angle under the light, the real hamon line seems to have a glow.


Authentic blades will have specific mekuki, or pegs used for the handle of the katana. They are usually made up of bamboo and serve to hold the sword together. They also act as shock absorbers for the whole blade. Extra mekugi pegs can be used to make the handle of the katana stronger.

Fake katanas will have the sword glued or screwed together. The importance of these bamboo pegs in the real samurai blades cannot be said enough. The samurai depended on these pegs to hold their weapon together.



The balance – how heavy or light it is compared with its length – of an authentic katana is also important. Authentic blades are usually light, with the balance point upon the tsuba.


The steel used to make authentic blades can vary depending on how it should be used. Authentic blades are usually categorized into five types of quality steel:

  • Tamahagane – 100% high carbon steel that is created from iron sand and gyokkan black sand during smelting process. This type of high carbon steel has a hard blade edge for cutting while being flexible enough to bend under pressure without breaking off.
  • Kazan Hagane – Crude steel created from carbonized iron sand and other types of materials. It is hard but has a bad edge for cutting.
  • Tamamagane – The highest quality steel, it is also the most difficult to create. Steel used to create tamamagane blades uses high amounts of manganese and low amounts of carbon, allowing it to be very tough and flexible at the same time.
  • Tama hagane or Chu Tomahagane – This type of steel has many different varieties that are usually made with high carbon content in order to make them easier to forge using modern tools.
  • Yoshamigane – High quality steel that contains various levels of molybdenum, vanadium and silicon, which makes it extremely tough and durable.


Finally, authentic katanas must be made by a Japanese swordsmith. Authentic blades are generally handmade from the beginning until until they have been properly manufactured into a functional weapon.

Authentic blades, including those that are bought online or seen in other shops will usually come with a certificate of authenticity to back up its veracity as a real katana. Authentic katanas require extensive training from masters who have made their own to produce them.
