I have a SwissTool. Great tool! If the Wave hadn't come out, it would be my fav, but I have to say I like the Wave a little better, due to one-hand opening blades, true needlenose pliers, and smaller size and weight. The Swisstool is a great one though -- I keep mine in my car. Also, it's extra weight adds one more tool feature to it...
Makes a damn fine hammer!
Wasn't impressed with the WengerGrip, particularly not at the price asked.
All my SAKs are Victorinox, though I have been tempted by a few Wengers. I have heard many compliments about their scissors in particular. They also seem to have a wider variety of tools. Saw one in SMKW catalog that had a T-10 screwdriver. May have to pick that one up.
