Mine is a Wave with full bit kit I keep in the car arm rest. I don't EDC a plier based tool anymore, just a Vic Ranger, but like to keep the Wave close in case I do. I last used it a few months back to cut a tree branch that had fallen over the road I was driving on.
I don't have a backup for day to day carry but I have a 24 hour bag that I grab anytime I'm going to be away from home and stores for more than a day or if I'm going to be more than 100 miles from home. In the 24 hour bag there is always an extra knife, a generic Chinese tactical folder that I had to buy one day when I forgot one from home, and an extra multitool or two, usually the Gerber MP I've had for 30 years or a Leatherman Crunch. Sometimes you just need a second set of pliers to turn a nut and bolt and sometimes locking pliers are even better.
