Loosen plaster or remove groutIt may not be the carpenter's best friend, but the sharp end of a bottle opener can be handy for removing loose plaster from a wall before patching it. It's great for running along cracks, and you can use to undercut a hole -- that is, make it wider at the bottom than at the surface -- so that the new plaster will "key" into the old. The sharp end of the opener is equally useful for removing old grout between your bathroom tiles before regrouting.
