I didn't carry a SAK or Multi-tool, then one day I read an article on
www.zdnet.com about the new Victorinox Cybertool. It was designed for computer techs and I was a computer tech - so I though it would be useful to get one. I went to a store that sold Victorinox & Leatherman and Gerber and a few other brands and asked about the Cybertool - they hadn't heard of it, but would ask the rep and get back to me. They rang me and told me a price, I said "yep, get me one" and picked it up a couple of days later. Now I've been EDCing that Victorinox Cybertool for about 10 years and I didn't even know what "EDC" was until a couple of years ago.
Over 10 years I've had no amazing life saving stories, but I have opened plenty of packages and I've dismantled & reassembled plenty of PCs. I've built quite a few PCs with nothing but my Cybertool because I just couldn't be bothered finding a screwdriver. Last year I was going camping and thought I'd take a couple of cans of peaches for a nice desert - it occurred to me that I had never tried to open a can with my SAK so I used it at home a couple of times and tried the can opener on my LM Wave too. The SAK can opener was noticeably better than the LM one so that was what I used when camping.
Both blades on my SAK are better than 'shaving sharp' so if I need to cut something in an emergency I know the Victorinox wont struggle with the task or let me down. I have not yet seen a hint of rust on my SAK - so it seems to be holding up pretty good. Actually the pen still writes and I haven't lost or broken anything at all on it. I still have the pen, toothpick, tweezers, stainless steel pin, 4 screwdriver bits & the tiny screwdriver that lives in the corkscrew.
I EDC both my Victorinox Cybertool and my Leatherman Wave (I got the Wave about 6 months after the SAK) and I always feel well equipped. The Cybertool has the better screwdriver and nut driver and can opener, the Wave has the better scissors as well as the saw & the file. It isn't often that I find myself lacking a tool I need!
I could tell you guys the story about the time that some nervous non-knife person got anxious because I had a SAK - but over 10 years that has never happened. No grief from others about the knife I carry is all fine by me!
