Swiss Victornox multi tool. A better tool AND unlike Leatherman none of your money will go to liberal causes.
You are aware Switzerland is a socialist country and a healthy dose of Victornox's money go towards liberal causes too? It does remind me I want to pick up another Leatherman however.
Here are the multitools I owned and used over the years.
Leatherman Supertool. It was nice and tough. The saw on it is totally awesome. It will still cut through thick branches like a knife through hot butter. It's blades were a fair length and sharp. The screwdrivers were tough and handy. The edges are a little hard on the hands when using the pliers and to release the lock on the tools requires moving another tool past 90 degrees and to tighten the hinges requires the use of a couple of pliers. Not too bad though, since I paid all of $5 for it. I wish it had a proper lanyard hole on it. I don't like how all the blades are on the inside though, but that was mainly for the ruler.
Leatherman Charge TTi. It is another full size monster with an S30V blade, awesome file, scissors, saw and has two screwdrivers with replaceable heads. This is my favourite one and it hard to beat for toughness. It also much easier to tighten up with a torq screwdriver. It also has a nice removable lanyard or clip option for when you don't want to put it on a belt in its case. I use this one at work.
Swisstool X. The thing has just about everything on it and it nigh indestructable. The tools on it aren't as big and impressive as the Leatherman Charge though, but it has more tools and you don't have to rely on adjustable driver heads which means less tools to carry around. It also tends to be cheaper than Leatherman tools. Probably my second favourite.
Gerber Suspension. What can you say? It is cheap. Very cheap. Of course the handles are so wide it hard to use, the tools themselves are relatively tiny and the clips to pull the blade out snapped after a few weeks of work and I couldn't find the receipt to get it repaired. It just doesn't compare to the others.
I was looking at one of the SOG Powertools. It has some nice toy factors to it such as the assisted opening blades.
You can get some good reviews, pictures and so on of various multitools at multitool.org if you need too. I don't know how good the other Gerbers are, but I been happy with the Leatherman and Swisstool so far.
