Kuttar

Kuttars were bayonet-like blade weapons that could be affixed to the end of energy rifles for hand-to-hand combat.

On Earth in India, the weapons were named katars.

The Albino's troops on Secarus IV used kuttars to battle Kang, Kor, Koloth, and Jadzia Dax in 2370 after their energy weapons were rendered non-functional by a tetryon particle field.
