So recently I got Mega Combo Wrench from BMI Supply which is a wrench that works all the bolts on a traditional C-clamp. It was only five or six dollars and after it came in and I used it on a show, I wondered why I hadn't ordered one sooner. It's really nice not having to mess with and adjustable wrench or several fixed wrenches. Like this, there are many other gadgets out there that are relatively cheap and make life so much easier. Has anyone else run across something similar, in that it simplifies your work dramatically or something else that makes you wonder why you didn't come up with it?
