Let's analyze each statement in the context of forensic pathology and wound characteristics:
Statement I: The wound will have bevelled margin, if the blade of weapon enters obliquely.
When a sharp-edged weapon enters the skin at an oblique angle, it tends to create a wound with a bevelled margin. One edge of the wound will be sharper and more defined (the entry point), while the opposite edge will be more sloped or bevelled as the blade cuts through the tissues at an angle. Therefore, Statement I is true.
Statement II: Bevelling can be produced by sharp weapons only.
Bevelling of wound margins is not exclusively produced by sharp weapons. Blunt force trauma, particularly when applied at an angle or involving penetration (e.g., skull fractures with inward or outward bevelling), can also result in bevelled edges. For instance, a blunt object striking the skull can cause an entry wound with inward bevelling and an exit wound (if present) with outward bevelling. Therefore, Statement II is false.
In conclusion, Statement I is true, but Statement II is false.
