Just got my Charge XTi in Monday's mail. It was supposed to come with a quick release lanyard ring, but didn't. I called Cabelas and they said they would ship one to me in 7 days. Well we will see. My sheath was also the nylon one.
Haven't had much time to play with it. Did compare it to the Wave. Open or closed they are about the same length. The Charge is about 1/8" thicker and a little wider than the Wave. So all in all the Wave feels like a slimmer and more compact tool.
I was a bit disappointed by the fact that the pliers had machining marks like scratches on it. The 154 cm blade had a bur on it. Nothing that can't be fixed with my dremal or some 000 steelwool, and honing on my Handamerica strop. Still...
Did try to fit it in the Wave sheath with the pocket clip attached. It was a very tight fit. When I tried to take it out the clip came off. Will think twice about using it with the pocket clip. The other thing I noticed is that twice when trying to close the Charge it was really hard to close like there was some kind of obstruction. I had to reopen it to close it. Every other time it closes very smoothly and easily. Don't know why this is. About the last thing I can say is that when closed and laid on a flat surface it wobbles. The Wave doesn't. Don't know why - maybe the torx heads are different thicknesses. When closed the thing feels more like the Wave than the Supertool ie the two handles have greater play with respect to each other - you can wiggle them.
All in all though the Charge feels solid. I have switched it with my Wave as my edc and give it a good workout. I also kind of wish that the Charge XT was available as I miss the scissors.
