Abstract：
:Sharp force trauma (SFT) in bone and cartilage has been studied extensively. This literature review summarizes knife and saw mark research. Researchers have documented several features of cut surfaces and successfully associated them with various tool characteristics. Most study designs are based on light microscopic examination, but other technologies such as micro-computed scanning, scanning electron microscope, and epifluorescence microscopy have been investigated. Researchers have worked with human and non-human material, and found that the presentation of SFT differs between the two. Furthermore, they have designed studies to control the parameters surrounding SFT (e.g., tool angle, force, direction) as well as not to control these parameters (real-world scenario) and have found that the trauma produced in the two scenarios differ considerably. Researchers have attempted to calculate the error rate associated with cut and saw mark analysis and have reported very different results. Several high profile cases of successful SFT analysis have been published and are briefly reviewed. Expert testimony based on cut and saw mark analysis has been found admissible, but not in all cases. Unfortunately, researchers have not consistently used standard terminology, a list of terms gathered from the literature is provided. Despite the extensive research, more work is needed. Methods that mitigate potential sources of error that are not dependent on analyst's experience must be developed.
