Handscrew Genius

So I recently bought six handscrews (two each of the 8", 10", and "12 jaw length). I put them on the rafter near the workbench and radial arm saw where I can reach them easily if I need them, and I can tell already I'll be using them a lot. They've been here less than a week, and I've already used them for several tasks:

As an impromptu saw stop,

To hold a smaller machinists clamp (that held a modified hook that I had cut and was filing smooth), and also to serve as a third hand to hold up a chair rail (I attached the handscrew to the door frame at the height where the bottom end of the rail went and set that end of the rail on the hand screw. I could then hold the other end with one hand and attach it with the other.).

If I was at all unsure of the purchase of these handscrews, I'm now convinced of their flexability and importance for workholding. In fact, I picked up 4 more of the Rockler 10" hand screws for the bargain price of $20.
