Ninja swords are shorter than the swords used by samurai. The reason for this was that a larger sword was often too big or heavy to allow the Ninja to run quickly or hide in small places. Also, the way a ninja used the sword was different to a samurai. Samurai would swing their sword, severing limbs and slashing at the opponent. Ninja, on the other hand, would stab with their sword. <= Ninjato

So, the swords the Ninjas used were real?

For I have heard a lot of controversy saying that the Ninjas only used Katanas as their main swords and that the Ninjato was a pop culture creation.

Katana's are much to cumbersome and large for the work of a ninja.
