Leatherman tools are great, especially the Wave/Charge models, but the steel used can be brittle and will snap if you use it beyond its tolerances, the same goes for their plier heads, since their now cast in good old Mexico and not made in USA as they were once were.
Personally, I would check out the Victorinox Swistool X for a large MT, or as was mentioned earlier, the Spirit. The fit and finish are much better than anything from Leatherman currently, you can access all tools while the tool is closed unlike the LM MTs. Plus the steel in the blades are better suited since it's the same as used in Vic SAKs and will flex before it would snap. They're also better when it comes to edge retention..
Since you don't seem like an ironworker or someone in the trades that would need a large sized MT, the Spirit may be exactly right up your alley. Good luck..
Cheers,
