Personally, I wouldn't go with a mystery steel knife that you hate. That makes no sense to me if it's supposed to be your 'go to' if something happens.
I keep a Mora classic in my pickup. If I need to cut and replace hoses, clean and replace a gasket, or just about anything else, it works.
Also, since I can't monitor my vehicle 24/7, it's inexpensive and easy to replace. It's also a highly trusted bush knife and a personal favorite.
Find your most comfortable, 'go to' knife at home, and get one of those. If that's a peanut, get another, if it's a busse battle mistress, well, get another. Just remember, this a 'what if' kind of thing, and 'if something goes terribly wrong' and I'm replacing heater hoses on the side of the freeway in the middle of nowhere, I want something I'M comfortable using. Been there, done that.
