Multi tool with decent 15mm

daccordi I still think the greatest multitool was the cool tool its based on an adjustable spanner with a chain tool in the handle. Putting the allen keys in the wrong way round gives you plenty of leverage to tighten up track nuts or take off pedals. I still have one and use it as my only chain tool and for doing up my phils as you can use the allen keys with the other part on to get better leverage than normal allen keys. I wouldn't want to use it all the time on track nuts though as you could end up rounding them, which I think maybe happened on my cheapo track hubs. Don't think thier made anymore and they are bigger than modern multitools but definately the most multi of tools I've used.

+1. lost mine at lands end when I was 16, and have been on the lookout for one since. After fruitlessly searching high and low, I'd figured that they'd gone out of production, when a relative surprised me with some nos in their local bike shop in north wales. Always have it in my tool kit, but generally only have to use a couple of 5 & 6 mm allen keys that always live in my bike jacket. Cool tool is definitely my favourite multi-tool. That said, the gerber lives in there too- I find it outshines the leatherman with its simple construction and lockable pliers- good for those stubborn teeth...
