Textile materials and evaluations

In the sport of Kendo, bamboo swords, or "Shinai", utilize cowhide in components such as the tip cover and the binding. However, being a natural material, the quality of cowhide varies greatly, with instances of it being damaged after only a few uses reported. In an effort to prevent accidents due to such damages, the authors investigated the impact durability of leather materials. They developed a repeated impact testing device and measured the number of hits until damage occurred in both natural cowhide and artificial leather. Assuming a Weibull distribution to evaluate durability, it was found that artificial leather can be expected to provide safety on par with, or even exceeding that of high-quality cowhide.
