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. (TNG: "Code of Honor")

Lieutenant Worf later kept one in his quarters, along with various other weapons. (TNG: "Peak Performance", "Reunion", "Redemption", "New Ground", "Cost of Living", "A Fistful of Datas")

The Klingon Duras sisters Lursa and B'Etor also kept such as glavin in their family home on Qo'noS. (TNG: "Redemption")
