It pretty dang big. I was contemplating the Surge or Wave, as they both had similar toolsets that I was interested in. Went to REI to handle them both. I don't mind the extra weight of the Surge, but man it is really a lot bigger than the Wave. And I realized that the Wave is pleny big for comfortable use anyway, might as well save the ounces for the times I'm carrying it.

One strange thing is the 'clicking' of the Surge. It's still a solid Leatherman, but when closed it rattles. Probably not a big deal, but at the same time doesn't seem quite right.

The removable/replaceable tool is kinda cool though.
