| Abstract: | In 10 tests, the linear velocity and rotation frequency of a thrown, pointed, razor-sharp shuriken were investigated using a high-speed camera. The linear velocity (5.1-9.87 m/s) and rotation frequency (0-4.46 m/s) determine the impact (0.91-3.6 nm) of this Asiatic weapon. An impact of 3.6 Nm is sufficient to cause a penetration depth of more than 3.5 cm within the regio ossis temporalis, the regio collis lateralis and the regio intercostalis. Legally, the use of this new generation of pointed, razor-sharp shurikens should be prohibited as "sports" apparatus. |
