Tantō

This traditional samurai dagger is great for close range combat and surprise attacks

The Tanto is a short dagger used by the Turtles. It is the smallest of the three traditional blades carried by a Samurai. The ones used by the Turtles are light, straight, and perfect for throwing. It appeared in episodes, such as New Friend, Old Enemy, TCRI, and Panic In The Sewers. In "New Friend, Old Enemy", Leo used these to cut Mikey free from his bonds when he was kidnapped by Chris Bradford and Xever. In "TCRI", Donnie used Leo's tanto to make a cut in the glass cell he and his brothers were trapped in when they were captured by the Kraang.

In "Slash and Destroy", Raph takes one out to use against Slash after seeing him beat Leo up, since his Sai were knocked out of reach earlier in the fight.
