Touring - The current tool kit

This tool kit has been assembled over 15 years and 60000 miles of touring. http://share.ovi.com/media/currentresident.bicycle/currentresident.10301 The crank puller has been filed down to fit the 15 mm wrench which also fits the pedals and both hubs. The bottom tool has been filed down to perfectly fit the adjustable wrench. The screw driver is actually a drill chuck there is a T20 bit and a multisize drill bit. The 8mm 9mm 10mm sockets came from a multitool and fit a 6mm hex wrench. A 12mm socket was filed using the Smith and Wesson diamond file shown to fit on the 10mm Allen wrench it fits the pedals. There is also a piece of a chain saw file. There is also a 8mm 6mm 5mm 4mm 3mm and 1/8 inch Allen wrenches. The 1/8 inch is for working on grip shifters these always galvanic corrode the 1/8 can be hammered into the 3mm socket to remove it. I suggest you get the multitool with a chain tool and the sockets but also buy the loose Allen Wrenches. You can carry a smaller wire cutters buy high quality here these are easy to break and you will be lucky if you don't end up with the broken handle through your hand. I also carry a water key that I recently lost.

This tool kit would be specific to a certain (older) bike. One could get away with even less with seal cartridge hubs, self-extracting crank, pedals with allen wrench fittings, chain with a power link etc etc. My preference too is for loose tools rather than a multitool. Small needle nose pliers (with a wire cutter) are useful for finding and extracting wire debris from tires. a "hyper cracker" to remove cassettes is easy to bring.

Knowing where to draw the line on tools can be difficult, however, requiring a sort of probability of needing versus weight/bulk analysis.

yeah but is nice knowing you have every tool to get you going again when you do break down .

If you go further, threadless headsets, external bearing cranks and Phil Wood FSA hubs allow you to pare the tool kit down further. A set of allen wrenches can replace all most all of the tool kit. The cassette body of an FSC hub can be removed with two 5 mm allens which allows access to drive side spokes without need for a hyper cracker.

For pliers/knife blade/screw driver/wire cutter/etc., a Leatherman PS4 is one of the handiest things I carry in my pocket.

Today Tony Pham was talking about using a hammer instead of a chain tool.
Very useful for many tasks.

And I didn't see duct tape on your list. Maybe coloured duct tape to match your bike.

Nifty idea with the crank puller, filling it down to match the 15mm

if you want to loose a few more tools, the new VO touring hubs disassemble without any tools. Strange concept, but the video seems devoid of trickery.
