Steve:

It's not a good idea to clean up the damage from a prop strike, sir.

If you want to experiment with an undamaged prop that's one thing, but there could well be concealed damage to the blade that will cause its later failure in service.

It is your airplane and your engine, but it could be someone else's eye if the engine throws a blade while running. I'd cut both blades to nubs and use it only as a dummy prop when doing engine work, New 18" props are not expensive.
