I also use them as a simple hand vice. Fixtures and jigs that utilize clamping can be taped to the jaws. The main bar can be replaced with a brass strip if you need a greater reach, but also need the smallness of these jaws. Household repairs? No. The slightly stouter Quick-Grips are much more rigid. These are for very light work and are the right tool for the delicate work of model building
I'd give a sixth star if I could!
