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.
