I just received my Charge Ti on Tuesday. I also have a Wave, a SuperTool, and a PST. Now, I don't use multitools as part of my trade. However, I carry a Sebertech M2 in my pocket, so if I have to go to my bag for the Leatherman, it means the situation does require something with muscle.
The Charge is a nice evolution of the Wave concept. Everything is more refined. All the tools lock, with an easy-to-use spring-loaded release on the end of each handle. My informal testing of the tool lock strength was that it didn't show any weakness under a load that is greater than I would ever think about applying to a multitool in actual use. The action on everything feels somewhat better than the Wave, especially the scissors. The belt clip/lanyard ring system is ingenious. There's a slot at the top of one of the handles that uses the same locking mechanism as everything else so switching from belt-clip, to larnyard ring, to nothing is as easy as opening and closing any of the tools.
I have always been a fan of the bit concept. I was a little dismayed that Leatherman didn't go with standard 1/4-in insert bits. But now that I have one in my hand, I appreciate why they did. Added to the exterior blades, their locking mechanisms, and the locking mechanism of the tool blades, regular bits would have made the handles too thick. Of course, the flattened bit form factor they use to overcome this challenge means the larger bit sizes of Phillips, hex, and presumably Torx have to be chopped off on the sides. I think there will be slippage when applying a lot of torque with these bits, but I hesitated to apply that much torque to my test screws because I was afraid of breaking the part before the bit gave way. Remember, these are relatively small bit sizes used by relatively small screws typically used to fasten relatively weak components.
The main blade is somewhat taller making it easier to control. It came from the factory razor sharp. I haven't had the need to sharpen it, but my gentleman's knife is 154CM and it takes an edge well. Honestly, I think SV30 would be wasted on this blade. It's still just a multi-tool blade. Too small and flimsy for serious prolonged knife work. I'm going to whip out my RSK1 or my CRK Project I for that kind of task.
