Construction: rubber head combined with a sturdy metal body for durable, longlasting use. Nonmarring rubber head: delivers controlled force without leaving marks or damaging delicate jewelry surfaces. Precision control: soft rubber face absorbs shock for gentle taps, while the metal core provides stable, consistent impact. Jewelryfocused design: ideal for fixing, aligning, resizing, or installing rings and other small pieces without scratching or denting. Versatile tool: also suitable for light metal shaping, small carpentry tasks, and engineering adjustments where a nondamaging hammer is required. Compatibility: works well on rings, bracelets, bezels, settings, sheet metal, and other soft or finished surfaces that require careful handling. Durable performance: metal construction resists wear; rubber head maintains its shape and protective qualities over repeated use. Easy to use: balanced weight and simple design let you deliver controlled blows for precision work. Typical use scenarios: Jewelry and installation: gently tap ring shanks, adjust bands, or seat bezels and settings during assembly or without marring the finish. Metal shaping and finishing: shape thin or soft metals and finesse small bends or edges in sheet metal without leaving hammer marks. Light carpentry and engineering tasks: perform final alignment, assembly, or adjustment work where surface protection is important. Why you need it: Prevents surface damage while allowing effective force for installation and shaping. Provides repeatable, controlled impacts for delicate tasks that ordinary metal hammers would ruin. Combines protective rubber contact with a durable metal body for reliability in workshop and jewelry bench environments.
