... The smartest invention since there is compelling!

Probably this clamp it all reports written and / or drafted otherwise - the leaves also by me certainly add nothing more extraordinary.
A single point I noticed what I would like to see in person (evtl.optional as an additional part?) Of this manufacturer:

Clamping and releasing of workpieces on the workbench / table must often be carried out with one hand, especially with bulky or large workpieces. One uses here the lever clamp as this falls at the open course in the most open end stop. A spring, which would only prevent this "Attracting attention", would in my opinion the "ne plus ultra" of this without this extraordinarily successful design!
Sure, there are also "right" hand clamps, but not for the envisaged purpose here this lever clamp in connection with the attack on the workbench.
Until then probably only helps individual initiative ....
