Which term describes the forward-and-back motion of a cutting blade that makes a back-and-forth cut?

Explanation:
Reciprocating motion describes a blade that moves in a straight line forward and then back along the same path, repeatedly. That back-and-forth linear action is what creates a back-and-forth cut. Oscillating would move the blade in a small arc around a pivot, not along a straight line. Rotating means spinning in a circle around an axis. Chopping refers to a quick downward strike rather than a sustained back-and-forth motion. So the forward-and-back cutting action is best described as reciprocating.
