I think it actually shaprens the sound a little, but it could just be me. I will say though that I've turned about 50 strikers in the last couple of weeks, and I've tried everyone before and after finishing them. Plus if they're finished I believe the sound will stay truer on humid and dry days, just because the striker won't suck up any moisture thats in the air. Just don't finish the last half inch of the tip and you should be golden.
