The katana, the longest and the most popular among the three is the sword that is generally referred to when an advertisement flashes that there are samurai swords for sale. 

 

The wakizashi and tanto, the two shorter swords are sold separately or as a part of the daisho or the set of swords the samurai wore.  The katana and the rest of the long swords such as the odachi and jin taichi are known as the daito, while the shorter ones like the tanto are called the shoto.

 

Most advertisements would boast that the samurai swords for sale are hand forged or made of high carbon steel because the real Japanese swords, which are neither just for decorative purposes nor for props, are handmade and the blade is forged with several layers of steel.

 

The decorative samurai swords for sale that are usually crafted with stainless steel and the scabbards are made of lesser-valued materials.  The modern nihonto, or the sword that is made in Japan is still popular despite the influx of imported samurai swords. 

 

Sword buffs who are knowledgeable with the types and materials of what these samurai swords for sale should compose of would surely test them for durability and if they come close to the real thing.
