The design of the ResQme has a clip that has a hole in it. You attach the clip (which covers the seat belt cutter) to an anchor point and when you need to use the tool, you simply grasp the body of it and pull. The clip remains attached to the seat belt pivot, and the tool comes away in your hand ready to use! The removal of the clip uncovers the seat belt cutter as well.

Hope that helps -
