A 24th century kligat

The kligat was a three-sided, hand-held Klingon blade-weapon.

In 2364, a Klingon female conjured up by William T. Riker for Worf wielded a kligat and tried to attack Natasha Yar using the weapon. She was stopped and disarmed by Worf. (TNG: "Hide and Q")

According to the script of the TNG episode, the female Klingon "holds a Klingon weapon – a kligat".
It is very similar in both name and design to the Capellan kleegat, seen in TOS: "Friday's Child".
