Ivanko Super Gripper loadings...
The torque calculations make me miss studying physics & engineering concepts.

It looks like a pretty decent device. $$$?
I have an Ivanko Super Gripper and I like it. However, I purchased a second one recently and the springs were much looser (easier) than on the first.  Thus, force curve calculations may not be the same for every device.  Does Ivanko claim that the springs are calibrated to a certain tension?

I plan on taking the new one back and finding another with similar tension, as the main point is to have one in the car or office and it needs to closely match the one I have at home.
