Abstract
A vise includes a base and two opposed jaws. At least one of the jaws is movable with respect to the other so that an object can be gripped therebetween. At least one of the two opposed jaws includes a frame and an array of polygon-shaped pins stacked parallel to one another. The frame has a bottom side and two opposed sides tapering towards the bottom side. The pins are disposed on the bottom side. Each pin has a cross-sectional shape such that when stacked together, the pins fit flush with one another and an area defined by the frame is tiled by the pins without any substantial gaps therebetween. The pins are oriented such that the tapering opposed sides direct force vectors to increase a pin-to-pin clamping force and the frame selectively clamps down on the pins such that the pins are held in place.
