What can I say? Like many of you I'm a toolaholic. I have six Leatherman tools of various kinds (original Super Tool, Crunch, Wave, Juice CS4, two Micras); three Victorinox (Swiss Tool and two small ones, slightly different, don't know the names); a SOG Toolclip; a Gerber Nautilus; and several of the lesser-known brands of multi-tools - which can't hold a candle to the well-known ones but there's one of them in my survival kit. The Micras are in my first aid kits. The CS4 is on the bedside cabinet with one of the small Victorinox, the other is in my pocket wrapped in a handkerchief. The Wave is in the wife's rucksack, the other Leatherman tools are in the Jeep. The Nautilus is on the coffee table as a kind of conversation piece, it's probably the least useful of all of them but the blade is nothing short of beautiful, and it's razor sharp. The torch on it is fun, but a bit useless like the scissors.
Difficult to say which is my favourite tool, probably the Swiss Tool, but my favourite blade is the plain one on the SOG Toolclip. It's wide, very solid and I certainly use it the most of any blade I have although I have to touch it up often as the steel isn't very wear resistant. The Toolclip has some harsh corners, and after it did a bit too much damage to paintwork and furniture when it was clipped in my pocket all the time I switched my EDC to the Swiss Tool. Although as someone else rightly said it's a little heavier than many, it does a great deal of work for me. Not a day goes by that I don't use it half a dozen times. It's both more comfortable and more convenient to use than many of the other tools, especially the original Leatherman which is harsh on the palms when using the pliers. The only times the Swiss Tool isn't on my belt are when I'm flying somewhere or suing somebody (they have metal detectors in Court these days, but at least they give you a cloakroom ticket when you hand them your knife). The velcro fastener on the leather pouch for the Swiss Tool could be improved - after a decade of hard wear it's pretty iffy, a stud would be better - but having said that it's never actually let me down. I've been thinking of getting another pouch for it. My favourite pouch is the one for the Wave, a close second being that for the Nautilus but it's actually a bit too tight for the tool. Perhaps I should use it more.

PS the SOG Toolclip bites. I mean REALLY bites. The worst is the large screwdriver which folds easily while you're using it and can trap a bit of skin in the process. The pliers bite too, nearly as viciously. They're the most uncomfortable I've ever used anyway, I think I should wear leather gloves when I use them.
