Common questions

How does a false-start kerf differ from a hesitation mark?+

A hesitation mark is a shallow repeat cut along roughly the same line, typically associated with a tentative or self-inflicted action. A false-start kerf is an abandoned entry at a different angle or position, pointing to the cutter repositioning the saw rather than hesitating on the same line.

What does a false-start kerf suggest about the person who made it?+

Multiple false starts around a joint or bone often indicate the cutter lacked familiarity with anatomical landmarks, which can help distinguish an inexperienced dismemberment from one performed with anatomical knowledge, such as by someone with medical or butchery training.
