Sword of Honor. A Klingon
sword reaching far into the roots of Klingon heritage. Even still, the
Bat'leth is used as a secondary weapon when battle is known to commence
between soldiers.
The
prop Bat'leths were made from a variety of materials, mainly though polymers,
as a real Bat'leth would slaughter actors, which would be bad. They were
seen on TNG, DS9, Voyager, and rarely Enterprise.
