So here's where I'm at:
Got an original wave, love it, retired to the car.
Got the Leatherman Sidekick - Love it, lightweight, as nice tools, AND spring action pliers.
Got the OHT - use it the most. Great tool, has stuff I need - Saw, blades, basic drivers, spring pliers, decent wire cutters, and doesn't have stuff I don't immediately need, like eyeglass driver (on the new wave, etc).
Got the Rev - budget deal, got it for like $20 at Home Depot. It's pretty nice, lightweight, and compact, but handles are asymmetrical, a little more so than the Sidekick.
Honestly, the REV pliers seem better that that of the OHT, in shape. I have photos (recent) on my Instagram feed, but basically, the OHT pliers only touch at the very tip, and are slightly off center. The REV pliers close up perfectly, and seem a bit thicker. However, I've used the OHT wire cutters to do harder work, the REV would just get jammed up, and then you'd need another tool to work it loose (with the OHT, you can just pull the handle apart, although it takes a lot to jam the OHT).
Also, the OHT is truly one-handed, and really quick to use and put away.
If you notice, the handles basically tell you what tool is there. It's a sweet design, and I've gotta say, it's probably my favorite.
It might be a little on the heavy side, but it's well worth it.
Word of wisdom, the sheath that comes with it isn't good for long term or belt use. Get yourself something nicer. I run mine in a Snake Eater Tactical pistol Burro.
