Here are a few.
1) Take an old plastic anti-freeze jug, lay it on its side, but a 10'' x 12'' rectangle out of the side. Clean it up real well, now you have a pistol disassembly box, all your parts can go in it and up to 8'' revolvers. It can also be used for cleaning, pour solvent it to soak, and when done, open the cap and pour it back into another sealed container.
2) Cheap pin starters, buy a set of tamper proof torx bits that fit into a 1/4'' magnetic screwdriver bit holder, the tamper proof torx bits have various sixed holes in the tip, the magnet helps keep the pin in place for starting.
3) I keep heavy leather straps around the shop, to use as an insulator for certain jobs, 16-20oz leather. That is nearly 1/4'' thick, it can be used on vise jaws, and with vise grips to prevent scratching.
4) left over Kydex plastic from my holster making days, can be used to make non marring vise jaw covers, heat up in the oven or with a heat gun and it is very pliable, will take about any shape you want.
5) Lead ingots, make good impromptu bench blocks, hammers and drifts.
6) I keep a 10' piece of surgical tubing for holding things together, like an action in a stock, while doing stock work and you don't want to be running the screws in and out.
7) Files, I recommend grinding one edge on your flat files to smooth, this is called a safe edge, when your trying to file a notch, only one side is cutting, especially opening up sight notches, or dovetails without it and your trying to file in a corner, your cutting 2 surfaces, not just the one you want.

If you need to loosen or tighten an ejector rod on a revolver, always put 4 empty cases in the cylinder 1st, to protect from torquing the ejector/ratchet assembly.
9) I have a large collection of the old S&W cleaning rods, that have the tube bent into a circle for the handle, I open up the circle a wee bit to allow me just hang it on a rod without sliding it off, just lift up, and I keep all pistol calibers with a plastic brush, brass brush, and jags, all ready to go, that is really about 12 rods, hanging on a pegboard, so I don't have to look for the individual pieces and assemble them,
10) I have 5 reloading presses, shotgun, metallic etc... but only one bench, so I mount them to 3/4" particle board, and C clamp them to the bench when in use, store the others on a shelf nearby.
Don't make fun of the loading room
