- Edged weapons
- Types of edged weapons
- knifes
- swords
- axes
- machetes
- arrowheads
- potential evidence from weapons
- fingerprints
- on handle from the assailant
- blood
- either victim or assailant
- fibres
- stuck in the bolster of the knife - from assailants clothing or victims clothing if the knife was penetrated through an item of clothing
- fingerprints
- knife characteristics (look at image attached)
- point
- The shape of the point is
therefore controlled by the knifes intended use.
- most likely part of the knife to break, potentially leaving opportunity for a physical fit.
- the first 5cm
- undergoes most stress
- different points are: drop point, raised point, tanto, top swage, clipped and spear. (look at image attached)
- The shape of the point is
therefore controlled by the knifes intended use.
- spine
- provides strength and weight to the blade
- belly
- The grinding of this section creates the cutting edge to the knife
- point
- Measurements
- Cross
section measurements are important to potentially match to stab wounds
- width and depth of the blade need to be noted - all in mm
- also measure the bolster as this could potentially match the bruising around the wound - if any is present
- Cross
section measurements are important to potentially match to stab wounds
- potential evidence from victim
- stab wounds
- The depth of penetration into the body is greater than the length of the wound on the skin.
- incised wounds
- The wound on the skin is greater than the depth into the body.
- chop wounds
- The wound on the skin is greater than the depth into the body, but the wound is not always a cut can be a crush from impact of the sharp belly ie cutting edge.
- wounds
- post mortem drying
- darkening of the wound
- loss of flexibility
- making an evaluation of wounds margins and angles difficult
- measurements provide information
- depth of the blade
- width of the spine
- double or single edged blade?
- angle of the cutting edge
- length of blade can only be estimated due to penetration may not be complete or the force may not leave impressions of the bolster
- post mortem drying
- direction - angle of the wound
- height of attacker
- hand weapon held in
- relative elevation
- relative position horizontaly
- sign of struggle
- knife characteristics
- position of attacker
- hand dominance
- stab wounds
- Types of edged weapons
