The length of a normal Japanese sword is about 70cm, but a Ninja sword is about 40cm, making it very compact. In addition, Ninja swords do not have the curvature of the blade, which is unique to Japanese swords. The short, warpless shape of the ninja sword was created to suit the activities of the ninja.
The warp of a Japanese sword is a very effective shape for slashing people because it can cut things with less force, and the longer the blade, the wider the attack range.
On the other hand, the main mission of the ninja is not to fight, but to conduct espionage activities by sneaking in unnoticed by the enemy. The ninja technique is a survival art, a fugitive art (escape), and an information gathering art.
To gather information, the ninja puts on a good face and enters into the enemy's midst sometimes. In other word, if they could accomplish their mission without fighting, so much the better, and if there was a chance to escape, it was important to do so without fighting.
For this reason, swords were made shorter and less warped in order to avoid hitting or tripping over obstacles such as trees or walls when running.
