Anyone ever had to use a shell extractor?

Should I put one in my cleaning kit?

I have a broken shell extractor, BUT I have never used it, nor have I ever wittness a 5.56 round broken in the chamber.  I carry one in my butstock.  See my sig line for my answer to most of these types of quesitons.

PS has any one out there had to use one?  Now Im courious.

All my friends as well as myself have them in our stocks. I or we have never used one BUT I was in a gunstore/gunsmith shop establishment when a Gent brought in an AR of some kind AND a nice varmint bolt gun of unknown brand in to  get both chambers cleared ! Seems he had too many reloads on the brass and the smith had to remove a broken 223 case from each weapon. Wow ,Had to plug the chamber & pour some kind of metal that has a low melting point down the barrel. The Metal hardend up in a min .& he put  a solid rod down the muzzle & tapped it out.
