A Glasgow Doorknocker is the
tool of
choice for
police forces and
Customs officers in the
United Kingdom. Essentially consisting of little more than a sizeable steel
pipe with
handles (
insert UNIX joke here), it allows easy entry through most non-reinforced doors by
virtue of its superior
momentum.
Its name probably comes from the fact that certain parts of
Glasgow (namely, the
Gorbals) are a little
primitive, and that the air of
rough and readyness it
exudes is similar.
