Males are routinely identified as both the victims and perpetrators of knife-related crime. Explanations have typically fallen into two categories: fear of further victimization (i.e., need for protection) and masculine gender norms (e.g., a display of "toughness"). However, these two works of literature have not yet been brought together to provide us with a fruitful theoretical understanding of why some young men engage in knife-related crime. The purpose of this systematic review is to consolidate and synthesize the available research on fear and masculinity as explanations for knife-related crime. In all, 23 studies were identified as meeting the inclusion criteria. The findings of the studies reviewed highlight the importance of considering the cognitive analysis of risk and perceptions of risk in young males' decisions to engage in knife-related crime. These perceptions of risk are shaped by previous victimization through a contagion effect and contribute to the development of an aggressive masculinity that justifies the behavior. However, it is not very well understood the role of fear contagion, and victimization in the shaping of masculine ideals within groups of young men involved in knife-related crimes. Additional research is needed to explore these findings and shed light on the complex interplay between these factors to inform viable treatment options for young men engaged in knife-related crime.
