Knives are rarely pushed into the body and withdrawn at exactly the same angle (unless the victim is incapacitated at the time of the assault). #
In addition, both the assailant and victim are in a highly charged state during an altercation, and movements of the principle parties are therefore highly fluid. Knife wounds reflect this dynamic situation, and are often ‘V’ shaped or irregular – also referred to as ‘twisting cuts’.
Rocking movements of the knife during an assault distorts the appearances of the wound, and the resultant defect is often much larger than would otherwise have been created by the same knife in a more static situation.
