Stab wounds upon bone are analyzed to interpret the weapon used and the physical context in which the attack occurred. The literature demonstrates that most research conducted pertaining to wound patterns has been carried out on defleshed and unclothed bone samples, not adequately replicating actual circumstances. For this research, six half pig torsos (Sus scrofa), fleshed (including muscle, fat, epidermis, and dermis layers) and clothed, were stabbed using three knife types, applying both straight and downward thrusts. Analysis conducted macroscopically and through a scanning electron microscope with an environmental secondary electron detector revealed a general lack of consistency in wound pattern and associated secondary effects. Consequently, it was not possible to establish wound pattern per knife type as suggested in previous research or relate it to stab motion. Advantage of microscopic analysis was evident in recognizing wound traits and observation of trace evidence not visible macroscopically.
对骨头上的刺伤进行分析，以解读所使用的凶器以及袭击发生时的实际情境。文献表明，大多数关于伤口形态的研究都是在剔除肌肉且未着衣物的骨样本上进行的，未能充分重现实际情况。在本研究中，使用三种刀具类型，以直刺和向下刺的方式，对六个带皮肉（包括肌肉、脂肪、表皮和真皮层）且着衣物的半头猪躯干（野猪）进行刺伤。通过宏观分析以及使用配备环境二次电子探测器的扫描电子显微镜进行分析发现，伤口形态和相关的次生效应普遍缺乏一致性。因此，无法像先前研究中所建议的那样确定每种刀具类型的伤口形态，也无法将其与刺伤动作联系起来。微观分析的优势在识别伤口特征以及观察宏观上不可见的微量证据方面显而易见。
