Cutting a rod tip?

[RC.]

When you say the tip got screwed up, do you mean the tip top (the top guide) broke? if that's the case, you can heat it with a lighter and remove it. If the rod actually broke, you can cut it and put a new tip on- do not use epoxy. They make glue sticks to put a new tip on. Epoxy is permanent and when the guide breaks (and this is common), you want to be able to get it off.

If and when you cut it, use the corner edge of a file and just go around it until you get through. Since the tip diameter is so small, you want to be delicate.
