I agree...with a caveat. Current multitools are poorly designed and ill fitting. They just don't fit your hand all that well. I've looked at the Crank Bros above and the Topeak Alien and others but they all are cumbersome. Ritchey made the CPR-9 back in the mid 90s and although it fit your hand better, it was mostly useless because it had no leverage.

The caveat is the Cool Tool. One of the first multitools and still, in my opinion, the best. It fits your hand like a real tool. The allen wrenches come off so that they are actually useful. If you need more torque you can put the allen wrenches in the end and extend the lever arm of the tool. And the chain tool is actually robust enough to be useful. They've saved me from a hike out of the woods more than once.

I was thinking my older than dirt multitool was a Cool Tool. Now I'm pretty sure it is.

The chainbreaker works just fine. I think I did get one additional allen wrench for either a light mount or a rack on my Mtn bike. Otherwise it has everythign I need on the road.

Does it look like this?

I made a 'sock' for it out of an old inner tube and put the allen wrenches that weren't all that common when it came out in there with it.

Are those allen wrenches 4,5 &6? That might be the perfect tool to pack along with our Kettweisel trikes. I wonder if I can still get one?

Useless hex keys? They all fit my bike.

Yep. 4, 5, 6 and a Phillips screw driver. They show up on Fleabay occasionally. I wish someone still made them.

Yup. For those who do not have one look carefully at teh allen wrenches, each serves as 2. Designed for function, not to look 'cool'.

I've used that exact same tool more than once to break chains. I've also used most of the hex keys on it too.

Ain't that the shizzle. I've never seen one. I wonder if the wrench is flat enough to be usable on the pedals.

Here are some more pictures (of other pieces to it).

Yes, the wrench can be used on pedals. It's also thin enough to be used on cones. It even triples as a tire lever. One thing I didn't show is the 7/8mm allen adapter that slides over the 6mm allen wrench. There were headset wrenches and a bottom bracket lockring tool. I have those as well but I don't use them anymore.

UPDATE:

Thanks for the input guys. Turns out, it's just my chain (Shimano) that is difficult to "break". I was successful at "breaking" a 20+ year old chain and a relatively new chain today while fixing up my friends' bikes and was surprised by how easy it was. Never mind, I don't need extra leverage anymore, I just might want to get a better chain.

10 spd chains are fundamentally different than, say, 8 speed and even 9 speed. with 10speed you can't pop out a rivet half way and then push it back in. You can't reuse the rivets at all and you have to be much more precise....it may not be a bad chain.

With Shimano,you have to use a new pin every time. With SRAM,you can rejoin the chain,even 10spd,as long as you don't push the pin completely out.

Could you please reference some source at SRAM to confirm that? Normally they use a PowerLink on their chains which doesn't require pins to be reused.

You are both wrong. You haven't been able to push a pin out and put it back for most chains for many years. SRAM has used a master link on their chains since the advent of 8 speeds. Almost all chains since then have used peened pins which have mushroomed heads to deal with side forces. The days of pushing a pin back in are long gone.

Sorry,but I just proved myself right. Had a few links of SRAM PC1051 laying around. Broke one,then put it back together. Was a bit of a PITA,but then I was using the crappy Wrenchforce chain tool from my kit with the slightly bent pin.

I carry a multi tool to make sure that bases are covered if I need something on the road. I also carry a chain tool (easier to use than the one on the multi tool) and usually also carry the four allen keys I use most frequently because I find a loose allen key easier to work with than the block that is the multi tool.

Sometimes I wonder why I bother carrying the multi tool at all, but figure the day I don't will be the day I need something more obscure that I get with the tool but don't have as a loose tool.

You don't understand the problem. You can drive the pin back into the chain on SRAM or Shimano. But that doesn't prove anything. The pins on both sides of the chain are expanded during the assembly process to stand up to the side forces and thiner plates for chains used on systems with 8 gears or more...perhaps even 7. When you push out the pin, you get rid of that expansion and the pin won't hold. It may take a while but you are risking a chain breaking by using the old pin.

I pushed out the pin and pushed it back in when I built my X, (in 08). I had to join two chains together to get the length that I needed. Put over 3k miles on it, never had any issues. When the chain reached the end of its useful life. I replaced it, again by pushing out a pin and pushing it back in, another 3k miles no issues.
I did the same thing this last spring, still going strong. Am planning to do it again this next spring.

BTW, All this pin pushing was accomplished with the aid of a Park MTB-3 multi tool.
