In 30 years in the fire service and EMS I have never had to punch a window or cut a seatbelt. Most "rescue tools" are marketing gimmicks that are too bulky to carry and usually end up at the bottom of your bunker pockets gathering rust. Besides, when you show up to a call you bring a big truck full of toys anyway!
Ronald McDonald called and he wants his sheath back.LOL.
I just gave one of those 4-in-1 tools to a friend for her birthday. She just finished her CERT training and had it on her wish list.
