Sharp objects like knives and axes are tools designed for cutting chopping tasks. However, their sharp edges also make them potentially dangerous capable of causing harm to people. Herein four distinct types were examined the penetration damages brought on by stabbing carbon Kevlar fabrics. The analysis stated damage patterns resulting from impacts concentrated factors that influence fabric penetration. Penetration force was recorded with different impact velocities material, revealing insights into punching behavior It observed at varying heights caused increased energy in both materials. Notably, showed minimal depth upon knives. Sheep foot point knife K3 exhibited maximum force, energy, due its pointed angle substantial weight. Additionally, this less surface area breaches fabric. In contrast, Drop K1, Clip K2, Cleaver K4 resulted larger damage, average areas 156mm 95mm fabrics, respectively. experienced least blunted structure. These findings valuable researchers studying crime offenses, manufacturing, protective body armor against stab threats. They contribute understanding dynamics such attacks informing development effective measures.
