-Kaginawa (Grappling hook): used when Ninja needs to climb a higher place such as a cliff and a roof of the castle. Sometimes it's used as a weapon, too.
-Kunai: it is generally used as a weapon to throw with Shuriken. Also, used for climbing and digging the ground and the wall.
-Shuriken: used as a weapon by throwing, sometimes stabbing or slashing. Sometimes poison is put on Shuriken. And there were many Shuriken with different shape.

-Makibishi: small, spiked caltrops to prevent enemy's pursuit as it injures enemy's foot. Ninja always has it in the case of emergency.
-Shinobigatana: Ninja's Katana(Japanese sword) for assassination. But it is shorter than Samurai's sword, so it is less capable of killing enemies.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgb8lpYBgbuFFrcuQMV9LVtKr3Bu-3WShf2H466Z1jGNMRDAtdXFwI0tAcIvZkWPATwuxcRF_Is39Lww3SYcyrmh3cVJXzqTswp8VNsAuxe9ia71Z7XzS76ktXhBN5k9h_5FJCAokMsFRxA/s320/275px-Ninto.png)

All of those Ninja tools seem really useful for his mission, but I do not think that Ninja can move fast with various tools. In my opinion, to be a great ninja, high physical ability and knowledge for use of tools may be required. At least, it can be considered difficult or almost impossible for "corpulent" people to become a professional Ninja.
