This LINE2design, 3 tool emergency rescue kit is great for the worst situations.
The clever design lets you use the shove knife tool from either side of the door. If the door opens inward (away from you), flexible blade in back of the molding stop and push or slide the blade to retract the latch. For doors that open outwards (toward you), the shove knife tool is slipped in from above or below the latch point and pulled to hook and retract the latch. Also used extensively in fire towers to slip spring latch locks during training exercises.
The LINE2EMS Window Punch is a spring loaded punch with knurled brass body for a secure grip. Stainless steel point for quick, sharp, accurate penetration. Use point to break glass for emergency entry, to help trapped accident victims.
