Magma Cutter

A Magma Cutter is a type of melee weapon deployed by the Chaos Daemon Engines known as Maulerfiends. In combat, the beasts will grasp hold of vehicles or emplacements and use its front Power Claws to hold its target while the Magma Cutters that protrude from its torso can focus the raw daemonic anger that burns inside it into a white-hot flame that can melt through rockcrete as thick as bastion walls.

Many an Imperial Titan has been felled by Maulerfiends clambering up its legs and shearing through its joints with its claws and pinpoint magma blasts and raking adamantium claws.
