Sharp force trauma is primarily caused by sharp implements such as knives, blades, or other tools with sharp edges. This type of trauma typically results in clean and precise cuts, as the sharpness of the implement allows it to penetrate the skin and underlying tissues effectively. The distinguishing feature of sharp force injuries is the way they cut the skin, often leading to incisions that can vary in depth and severity, depending on the force used and the sharpness of the weapon.

Other types of trauma, such as blunt force trauma, often involve the impact of heavy objects, which would cause different types of injuries, characterized by bruising or lacerations rather than clean cuts. Rusty implements may introduce additional bacteria into a wound, complicating injuries, but do not inherently cause sharp force trauma unless they are also sharp. Firearms cause blunt and ballistic trauma, resulting in different wound patterns compared to those seen with sharp implements. Thus, sharp force trauma is specifically linked to the use of sharp tools.
