I recently had a project that required a *lot* of clamping force in 6 different places across 28 different cut jobs. After tightening and loosening the clamps over 300 times for this single job, I decided to make a clamp wrench.
It turned out to be surprisingly useful and I use it daily now. I made mine out of a 1" thick piece of high density urethane at 48 pcf density - though 3/4" plywood would probably work fine, too. I rounded the edges on a router and it fits perfectly. I hand tighten the clamp until I feel some resistance, and then I use the wrench to give it another half turn or so and that's been sufficient for all of my jobs since.
Please feel free to use the attached DXF (exported in inches) to make your own it you feel it might be useful to you, too:
That's awesome! I had considered going that route, but I wasn't sure if I'd just be suffering from the same issue as the smaller knob (I had some tendon weakness in my wrists due to a medical procedure).
I think I might go ahead and whip up one of yours so I have one of each style handy; thanks for the share!

I decided against a handle to make using it faster. I discovered that the added diameter allow me to flick it and have it spin freely on/off. That's nice when changing to drastically different material thicknesses. I just hit the threads with oil once in a while.
