I would recommend a Leatherman Ti Charge like mine. It’s like an upgraded version of the Wave. It’s the same as the Wave, except better blade steel (154cm), titanium scales, and bronze bushings so the tools don’t clump together when you try to use one. I know you like nice custom knives, so I think you’d like it. When I was choosing, I was debating between the Wave and Charge. I decided since it was something I’d be carrying for several years every day, I might as well pay the extra money and get the nicer one. They’re pretty heavy though, they weigh like a half pound.
I also got the “bit kit” for mine, it was like an extra $20 on eBay. They take special shaped bits, not the standard ones. You can “convert” standard bits to Leatherman bits if you have a benchgrinder and locking clamp pliers to hold it with. With the bit kit you have all the unusual shaped bits like hex or star that might come in handy. I don’t carry the extra bits though, I leave them in the truck. I liked the idea of the replaceable bits, because if you over torque a screwdriver bit and bend it, you can just replace the bit instead of the whole tool.

I also have all three models of Craftsman multitools. I like to use them for really hard work where I’m afraid of damaging my Leatherman. Since they’re made by Craftsman, if anything happens to them, I can just trade them at Sears for a new one.

Here’s a couple threads from the Swamp that may help too.
