This is what I keep in my (right front pocket) leather organizer
In the front two exterior pockets, the sewing kit fits in on the left and the Knipex fits in the right.
It's basically a mini commonly used hardware and medication pouch. I use fishing line for sewing in situations where I need strong thread, and I have various size needles in there too. The Altoids Smalls tin has a few of my most commonly used medication for me and my family. The Rolaids are for my heartburn unfortunately.
Literally came here to comment, "Are you guys going on some kind of MacGyver-style adventures that are wholly unnoticeable by the rest of us?" I suspect the answer is yes.
I have some of that stuff in my bike's pannier, but I don't know why I'd want it on my person. Today it's just keys, phone, wallet, a surgical mask, and a hand towel (Tokyo be sweaty and humid)
I use mine for bending sheet metal and holding objects while I saw them/work with them. I like to build things in my spare time, so I use them frequently for gripping, crunching, crimping, or wrenching sometimes.
apart from all the plying, I took out many splinters with it (it's a relatively precise finish). It helps with kids' shoelaces when they make a mess of it. Handles are good enough for prying. Forgotten staples on things… list goes on and on. It's much lighter than a multi-tool. You forget about it until you need it (a multi-tool reminds you that it's there in your pocket, they are hefty
That steel wire is lovely. I keep seeing people with pliers, thinking "why?" then ending up in a situation that could be fixed with pliers.... My scissors usually suffice though.
It's just picture frame type wire which is super cheap and super strong. I have a lot of it at home, and I've had to replace it a few times now. If I didn't already have a lot of it though, I wouldn't go out of my way to carry it because strong paracord or thin rope could be just as effective.
I carry galvanized wire, the kind that's just a single strand, in my vehicle's tool bag. Along with some pliers it can do a whole lot more than rope or string. Binds things super tight. I can fix a fence, animal carrier, tons of things on a vehicle or structure... it's obviously not the best fix for most things, but it's adequate to solve an astonishing amount of problems, especially if you carry a couple screws. Harbor freight sells it in convenient little rolls for around a dollar.
