From Halopedia, the Halo wiki
The Kig-Yar aboard the Minor Transgression used laser-cutters to disconnect the Luminary from the ship's main power grid, which was considered heretical. As (almost) demonstrated by Zhar, a laser-cutter can be used as a deadly weapon if the need arises, as it could easily cut through armor and skin. In April 2553, Bakz used laser-cutters from the Paragon to create an exit when he was locked inside a compartment on the Pious Inquisitor.
