Very nice job!10/10 for originality!

Just an idea for that 1/4" drive:- Purchase a 1/2" low-profile socket head cap screw (SHCS). This screw has 1/4" hex.- Cut to length and turn the threaded portion to the same pin size of the Rebar.- Drill two small holes on the screw's head. Drill two small holes on the Rebar handle (same size, same distance). Use two pins to "lock" screw in location.- Drill and tap a hole on the turned end of that SHCS, same thread size as the Leatherman pinBasically, I am suggesting a fabrication of the female screw replacement with addition of the 1/4" hex and dowel holes. Will be tough to tap the screw. If I am not mistaken, stainless screws are available.

But I locked the screw by drilling through pliers' eyelet* and peeled screw and hammering fi 3mm perpendicular pin there with some Loctite glue. So the screw with hex socket was locked in pliers, not on the Rebar handle as you suggested. My solution worked perfect till I used allen-hex (6mm-1/4'') bit to unscrew old, rusted screw in my bike. The locking pin started to be loose and finally teared screw into two due to enormous torque there - the screw was 12.9 rank, so the most durable on market! I don't think the two holes in Rebar handle (as you suggested) could resist that as the handle is pretty soft stainless steel.*drilling in LM pliers eyelet was the worst 3 mm in my life. The steel there is so hard that even cobalt drill was not sharp enough. Finally I used cheap carbide masonry drill I must sharpened every 30 seconds of drilling Never again!
Wow! That is some nice modding!
That is a regular SHCS. A low profile SHCS has thinner but wider head, thus you have some material to work with. The 2 pins in my idea provide 2 additional positive "locks" to the screw on the other side alone. We are talking about metal on metal here, not some glue. You also need to hold the close tolerance between the pins and the holes, make them slight press fit. You also need correct drill size and style, and proper set-up for the job, on a milling machine to ensure the holes are round, to size, and square to the surface. For the drill, you need self-center carbide drill used in metal working industry (I personally like those MDS/ MDW drills by Sumitomo). Lastly, the pins need to be hardened steel for strength.

In my place I can barely find screw with 1/4'' hex socket, and I've never seen those with wider head
If you have problem with sourcing imperial-sized screws, why 1/4" drive but not 6mm? Shouldn't it easy to buy 6mm hex bits?
