Leatherman Wave. One handed opening blade, diamond hook sharpener, along with all the standard bells and whistles. Had 'em all at one time or another...used this one for about 7 years now, can't see chaniging. By the way, the gerber pliers are TERRIBLE...easy to open but if they slip while you are cranking on something to tighten it you WILL get a very nasty blood blister for you trouble when the handle pinches your hand, the handles come too close together to be safe.
