Welcome newguy! I carry a Leatherman Kick at work every day and a Leatherman Wave everywhere else. I use the Kick at work as its cheaper and I use it to cut tubing and repair equipment that is coated in crude oil and assorted nasty chemicals. I wish the Kick had a scissors but the knife blade handles most cutting jobs I encounter.
The Wave has a lot more options and I think the new ones have a diamond-coated file. That would work as a very slow metal saw, wouldn't it? I love it's one-handed-opening blades and seemingly endless supply of tools. I don't use it at work as I want to keep it "food safe" and so uncontaminated.
Really, if you are only getting one, I say get the Wave.
