While yielding to no one concerning my high regard for the Wave, I don't consider it a toolkit item. Toolkits are for dedicated tools, while a multi-tool is something to have on your person when you are away from your purpose made kit. As a former mechanic, I am very much in the mindset of using the proper tool for the job, but even so, I manage to use my multi-tools multiple times a day for all sorts of things. There have been incidents when my Leatherman came in handy, even with toolkits not far away, but the important thing was that it was on me when I needed it right now. Other than that, for tightening a nut, a wrench beats pliers hands down, etc.
Yeah, I like the right tool for the job. There's a small canvas army tool bag behind the seat of my truck, and in it are real Channel locks, Vise grips, screw drivers, and medium adjustable wrench. The pocket size Leathermans to me are more harry homeowner small jobs on the fly kind of thing.
Right tool for the job.
