From Memory Alpha, the free Star Trek reference.
The
glavin is a type of weapon used for ritual hand-to-hand combat by the
Ligonians. It is a large glove with a recurved claw at the end, and covered with dozens of spines tipped with poison.
Lieutenant Natasha Yar used a glavin when she fought
Yareena in
2364. Yareena died when she was grazed by one of the spines, but was later revived aboard the
USS Enterprise-D. (
