In lecture, we talked about the difference between striations from a knife and striations (called kerfs) from a saw. We can use the striation appearance and direction to work out the motions behind an action. For instance, saw marks can show the push and pull motions separately, but can also show if the person changed angles of their cut. Identify the direction(s) of the striations in the image below. What does the appearance you about: 1. The nature of the weapon (e.g., saw vs knife) 2. The movement of the weapon (e.g., multiple strokes in one direction, multiple strokes in multiple directions, etc.) 41 NOV m 4 A W tv zoom 3 at g 23 at jpeg ewor
