The human stabbing action is a dynamic interaction between the assailant and a victim, resulting in sharp force damage. The morphology of such damage is influenced by multiple parameters before, during, and after the stabbing incident. In forensic investigations , examining wounds and textile damage provides critical information about the implement used, the method of stabbing, and the associated physical interaction between the assailant and the victim. This information aids in reconstructing events and determining whether injuries are homicidal, accidental, or self-inflicted. The assessment of tissue and textile damage involves qualitative analysis followed by hypothesis testing of simulated stabbing incidents and damage reconstruction. Currently, these reconstructions are manually performed by forensic practitioners, but variability exists in stabbing actions both between and within individuals, leading to limitations in accuracy, repeatability, and reliability. The present review represents the most current comprehensive overview of the factors affecting sharp force damage. It discusses the process of damage analysis with an emphasis on textile damage and discusses both manual and mechanical simulation methods used in research and forensic casework. It highlights the capabilities and limitations of these approaches, offering directions for future investigations and their forensic applications. Tables detailing the design and results of manual and mechanical experiments conducted since the 1920s are provided to assist operators. Finally, advanced methods , such as robotic arms that mimic human motions, are discussed as potential solutions to some of the current limitations, with the aim of enabling standardization in sharp force damage analysis and reconstruction.
