In comes the OHT. With this tool, you just grab hold of the handle and give it a healthy "flick," and the pliers fly out willingly. Let one of the handles go, and the spring action opens them all the way up, and you're ready to go to work. Oh yes, unlike other competitors, these are spring loaded for ease of operation. When you are done, you simply grab the release buttons on either side and turn it over to allow the weight of the tool to close in on the pliers, or use your pinky to push the handle up over the pliers head.
2 tank wrench, can/bottle opener, #2 Phillips screw driver, small, medium, and large flat blade screw drivers. All of these tools can be accessed, as said above, by orientating the tool in your hand to access what you are looking for. And did you see the coyote tan body? It has each tool shown in a sort of pictograph so you can easily identify it until you memorize where they are. Is it necessary to have this? No. But it does at some cool form factor to it. Boasting a total of 16 tools, if you count the usual suspects on the pliers head - needle nose pliers, regular pliers, removable wire cutter, and hard wire cutters, you have a formidable tool to conquer 95% of the tasks you would employ it for.
When you talk about overall sizes, the Wave on the left is definitely the runt. The OHT is smaller than the Supertool 300, though it weighs more. The Supertool is the hog of the group. The head on the Supertool's pliers is also larger and seemingly more durable, but the outer dimensions coming to the tip of the needle nose pliers allows it to get into tighter spaces.
I have included a video with a lot of the same information above, but it also shows a demonstration of tool operation, as well as one-handed access to the various tools around the handle. I also compare the Supertool 300 and the Juice S2 in a 3 dimensional format instead of the usually pictures I normally take.
