This is a PVC NINJA KUNAI. Ninjas used kunai not just as weapons, but as tools as well. Here are some of their most common uses. 1. Use as a stake or lever Kunai have a broad blade, rather than a sharp point, so they could be used to climb between stone walls when infiltrating castles, or to lift heavy objects using the lever principle. They were also used to prune branches when entering the mountains, making them an indispensable tool for ninjas. 2. Use as a defensive/strike weapon Kunai were primarily used as tools, but they could also be used as weapons in emergencies. While they were difficult to slash with like a sword, they could be used to deflect enemy attacks and attack with thrusts and strikes. 3. Use as a throwing weapon Kunai are not as lightweight as shuriken and are not exclusively for throwing. However, they were sometimes thrown to intimidate enemies or to move distant objects. Sharply sharpened kunais were particularly capable of inflicting fatal damage at close range.
