Yeah, I’ve got a pair of Leatherman EMT folding shears with a fold-out webbing cutter. The scissor blades are serrated and seriously heavy duty, I carry them just in case, I do roughly 40-odd thousand miles a year all over the country, and you never know if a situation where it might be necessary to get someone out of a vehicle quickly might happen right in front of you.
Driving over the Severn Bridge this afternoon I noticed several cars on the opposite lane hard-shoulder, with people standing around, but traffic going past, then I noticed a van lying on its side and the traffic starting to build up, so it had only happened a minute or two prior; difficult for someone to get out in that situation, being able to quickly slice the belt through safely to allow a person get themselves out with help might make all the difference.
I hope I never have to use it.
The actual shears are amazing for slicing through all sorts of stuff, though.
