Those rescue oriented tools are fine for keep in a vehicle (and I do keep one in vehicle) but I'd never carry one on person. Just way too specialized to dedicate the space for them, I've been through almost 30 years of my life without ever needing one.

I'm sticking with my pocket knife.

I also have had problems with the window punch on the ResXXX whatever tool. I bought a spring-loaded metal punch at the hardware store instead and keep that in the console of my truck where it can be readily stolen by the guys who wash and vacuum out my truck.

It could be any of a number of reasons. For example, it's highly likely to be a legal issue (trademarks). "Rescue Me" is either already trademarked or impossible to trademark because it's too generic. In contrast, "ResQMe" is easily trademark-able. There are other reasons not to use "Rescue Me". I'm sure the company, which is equipped with more information, has their reasons.

By the way, I wouldn't mind being the founder of brands like "Cheez-It", "Froot Loops", etc. Those brands are so ubiquitous that most people probably don't even realize the words are misspelled. It's like the branding bypasses the conscious and goes straight to the subconscious...perfect.
