I can only imagine, but it must be brutal.
I have this klein set. I like it a lot. I carry extra bits in one of those rubber coin purses. You squeeze and it opens.

Sorry to comment on an old post, but I'm going back to the whole 1/4" hex bit adapter thing. I have a plastic do-it-all separator box that I use for almost every task. I just used it today, to tighten the screws on a tomahawk sheath. I honestly don't need a dedicated hex bit driver, because I keep that box in my vehicle. I even have a 1/4" ratchet in there, with an extender, a universal joint, and most of the Imperial and metric sockets I need. I literally have every type of hex bit anyone would need. It's extremely handy. I don't have to put extra pressure on my spine by carrying my heavy tool box out to my vehicle, when I need to fix something small.
Regarding a 1/4" hex bit adapter for my original Leatherman Wave, I own a lot of knives and camping equipment with small screws, bolts, and nuts that need to be tightened. The fasteners on knife handle scales, folding knives, and knife sheaths, typically aren't Phillips or flathead. They're typically torx or Allen. I've even seen fasteners that require square bits. I realize I don't go back country camping anymore, due to my disabilities. Consequently, I always have my SUV when I got camping. But, if manage to get healthy enough to go back country camping and/or hunting again, I'd like to have the correct bits to tighten the fasteners that need tightening.
I think I'm going to install a hex bit driver that takes up one half of the interior of my original Leatherman Wave. I can put the scissors, can opener, and any other tools that will fit on the other side. It seems wasteful to spend money on a new, expensive multi tool, when my original Wave still works well. Yes, the interior tools don't lock like newer multi tools, but it's honestly not that big of a deal.
