A Jewelers vise will hold delicate pieces of jewelry. The vise is adjustable at the base, and the tip rotates so that the piece can be angled any way needed.
A soldering vise pivots at the bottom to offer maximum orientation while working. It has rubber faces that can be used to prevent soft materials from becoming damaged. These rubber faces are removable when working with heated materials as in soldering.
Some vises come available with suction cups on the bottom. This prevents having to screw the vise into the work area. It has a lever that can flip to engage the suction cup. The head of the vise can also be pivoted.
Basic woodworking vises are made of steel and can be attached to either the front or back of a workbench.
Another vise example that is very versatile, mounts to any workbench and can be pivoted to hold materials horizontally. It has a spring-loaded quick release so it can open or close easily. A foot release can be put on the floor, allowing the unit to be opened and closed hands-free.
