Cutter
Cutter was the term for people who worked as part of a mining team and used phasers to split asteroids so excavators could access the valuable resources inside. 

A Starfleet ensign, who shot himself in the foot with a phaser during the Battle of Ajilon Prime in 2373, told Jake Sisko that after his court martial, he was definitely going to sign up for the next mining expedition to the Gamma Quadrant, where he could become a cutter. ()
