Hi dlafferty. As a Leatherman and Wave owner, let me give you my experience with the tools. With the one-handed opening, this only works on
two blades-the serrated and straight blade. You have to use your right hand to open these blades. If you want to open the saw and file (or scissors for surge) blades one-handed, you would have to use your left hand. So what it really is is that one-handed opening only works for only two of the blades. If you find yourself using the clip point blade or serrated blade a lot, then the one-handed would be good for you. If not, then it would be better off going for the Vic as they are much cheaper than the Leatherman's.
The other main difference with the Spirit and Swisstool are the screwdrivers. Whereas the vic has around 3 flat screwdriver and one phillips, the Wave/Surge/Charge come with this bit adapter where you have to carry about 2 to 4 bits to equal the number and kind of bits that are attached to the Vic tools. I suppose if you want the option of more bits to use with your tool then go with the new Leatherman's (the Charge Xti has 2 bit holder as well). But if you're happy with a small, medium, and large flathead and a phillips then go for the Vic's. Bear in mind though that the selection of bits for the Leathermans are just some commonly used torx, hex, sqaure, pozi, flat, and phillips. Quite a lot, though not complete. The torx and hex bit, for example, are not security. If you want to learn more about the array of screw out there then go to
these webpages. The other problem is that they are proprietary bits. If you need other bits, for example spanner and clutch bits, Leatherman doesn't sell those. In fact,
these are the only bits that can be bought with the Leatherman proprietary drivers. If you want to use the more common and wide selection of 1/4 hex bits then you would have to buy the
tool adapter from Leatherman, as the bit holder cannot accept standard 1/4 hex bits.
A thing to keep in mind about the bit holders for the new Leathermans is that they are stubby. Usually, screws are fastened in deep holes, and the stubby bit holders of the Leathermans couldn't access these holes. I guess the same is true for the Victorinox's. The small screwdriver, for example, is on the head of the bottle/can opener. Just the same some of the vic screwdrivers wouldn't be able to access small holes where these screws are screwed.
My
thoughts about the screwdrivers on multitools is that they generally fall short. I think you're better off having dedicated 1/4 hex bits with hex driver (like the one that comes with the Swisstool CS plus), an equivalent can be easily bought cheaply in any good hardware store.
I generally carry my multitool now for the blades, and in this regard the Surge really works for me. Almost all tools can only have four large blades at a time. It's a toss up between a straight-edge knife, serrated knife, metal saw/file, wood saw, scissors, remgrit saw and diamond file with crosscut file. So it's a combination of 4 out of 7 blades that you can carry at any one time. With the Surge, I can have four of those blade attached to the tool and the three others in my pocket ready to use with the tool, thanks to the blade exchanger.
Hope this helps.
