Cork Knocker for Pipe

What is a cork knocker and what is its purpose?

The "cork knocker" is simply a small, round-shaped piece of cork. It is used by pipe smokers to help remove "dottle," or unburned tobacco, from the bottom of the pipe bowl after smoking.

Since a pipe can be easily damaged by tapping it against a hard surface, the cork knocker provides a soft, yet firm, surface that is safe for the pipe. By gently tapping a pipe against the cork knocker, it helps to dislodge the dottle and keep their pipe clean. The cork knockers are often fastened into ash trays for convenience, but they can be used anywhere the smoker wishes.

Champaign corks are excellent cork knockers. You can easily screw one or glue it on your favorite ashtray.
