That covers a lot. Do you want light, medium or heavy duty?Any specific requirements?
Surge: Weight and bulk. You'll need either the pocket clip or a belt sheath to carry it. It is not really a pocket carry tool at all. I dislike all LMs with outside opening tools due to their propensity to have the tops of the other tools to cut into my hand. IT has the bit driver, meaning any of LMs bits can be used. Charges can be expensive, depending on how you've got them configured. Some have higher end blade steels (S30V), and many have the cutting hook on the serrated blade, a seriously handy tool. I've not justified their cost, so I have yet to own a Charge. The Cabela's orange G-10 is my favorite, but I can't really afford $180 USD. I plan to travel to the Cabela's about two hours from here to check one out in person this summer. Wave. Same cutting into my hand while using the blades with heavy pressure issue with the Surge. But, I can carry it all day clipped to my pocket. No awl, which is a tool I require. Leatherman recently produced a model for Dutch law enforcement which is perfect--awl in place of can opener; cutting hook serrated blade from Charge. Unfortunately, not sold to the public. ST300; my farmwork tool. I am carrying mine now., in a MOLLE XL sheath threaded onto my belt. A very tough tool, easy to use with gloves. My complaints are that some of the smaller drivers are soft--I've twisted the smallest once twice. Weight is an issue here too. Normally I carry a Rebar, but had recently misplaced it, so I'm back to the ST300. There's a removable bit adapter that either alone, or fitted to the Phillips screwdriver, allows you to use both LM and 1/4" drive screwdriver bits. SwissTool. I have one of these as well. Just as tough as the Super Tool, but with typical Swiss finish. A little thinner and lighter than the ST300. Mine does have a common flaw in that the pliers handles don't line up. One of my complaints with SAK drivers in general (including the SwissTool) is that they are a little too highly polished. But, higher quality and better finished than most Leathermans I have owned. Good tool selection and design as well. I just can't open it with gloves on. Spirit. If the SwissTool is too heavy, I think you'll like it. I don't own one yet, but hope too. It can be had with scissors, as can the SwissTool. The good thing about Swiss MTs is that both the Spirit and SwissTool have lots of variants. The SuperTool has just three: standard, EOD, and the new "M" intended for firearms enthusiasts and the military. Just do what I do, if you find
Heavy. Well, multitool heavy duty
Cons:You can't get enough of any of those MTs...
A lot of this is subjective. I don't find the Surge to be too big - to me it is the perfect size for my hand. I find the Wave and Charge to be too small.Aloha, perhaps having a can opener is only a con if there is something else you would rather have in it's place.
