Why should a tuning fork be set into oscillation by striking it with a soft rubber mallet rather than with a hard metal mallet?

Striking it with a hard mallet excites higher order modes rather than mainly the fundamental. That is because a hard mallet impact causes steep stress waves with high frequency components to go back and forth in the fork.

That is my educated guess at the answer. There is probably a better way of saying it.
