In a stab wound from a single-edged knife, the wound shows:
- A One end is sharp, the other is blunt and squared ✓
- B Both ends of the wound are sharp
- C Both ends are blunt and squared
- D Circular wound with no specific end characteristics
Correct answer: A. One end is sharp, the other is blunt and squared
Explanation
A single-edged knife (like a kitchen knife) produces a stab wound with one sharp, clean end corresponding to the cutting edge and one blunt, squared end or split end corresponding to the back (blunt edge) of the blade. A double-edged weapon like a dagger produces a wound with both ends sharply tapered. This characteristic helps identify the type of weapon.
