My irons have square grooves. They make mincemeat out of most balls, but the covers are tough enough to prevent them from becoming out of shape or cut.

How much damage can I repair on my ball?

f'rinstance... usually, my irons peel some of the skin pretty deeply into the cover of the ball. Some of the peeled plastic comes off when I clean the ball for putting but sometimes it leaves very rough surfaces on the ball. Can I use a knife or rough surface to cut or smooth the rough surfaces on the ball?

Also, once I (with my fingernail) peeled back some of this damage (I was just trying to smooth out the ball), and it peeled back a great chunk of plastic from the skin. This is rare, I guess, perhaps a manufacturing defect, but would I be able to take the ball out of play (it left a scar almost as deep as a smile)?
