Try to remove a double-ended screw from a watch bracelet sometime. It can be an exercise in frustration, but if you use the new screw removing tool, the job becomes easy. Three Swiss-made blades (1.0, 1.4, 2.5mm in diameter) are friction fitted into a solid aluminum block. Just fit the bottom screw slot over the right blade and easily unscrew from the top. Makes life simple and assures that the bracelet will not be damaged, if used properly. Measures: 1-1/2" x 1-3/16" x 1-1/16"
