Propeller key question

[SunbeamIV]

I just brought my propeller into the shop to have a ding on the trailing edge repaired and the technician commented that the current stainless key wasn't recommended, and suggested replacing it with a bronze one.
Is there any reason to stay with the existing stainless one?

You want the softer key so it will shear if you hit anything big.

Makes sense. Thanks, Jeff.
