A karabiner with a pulley built in.

The DMM Revolver’s integrated roller wheel lets rope run smoothly through the biner, so you can redirect a line, haul a saw or rig a quick mechanical advantage without carrying a separate pulley.

The Locksafe gate locks itself and takes three distinct actions to open, so it stays shut on the tools. A keylock nose means nothing snags clipping in or out, and I-beam forging keeps it to 70g for 24kN of major-axis strength. The pulley wheel works with loads up to 11kN.
