  "abstract": "This disclosure describes a powered hand tool incorporating a vibration reduction system that decouples the handle from the tool body through a tuned mass path. The system addresses the problem of hand-arm vibration exposure, which typically limits the duration of tool use long before component wear dictates replacement. By strategically integrating an inertial mass and elastic elements, the design attenuates vibration energy within specific frequency bands, primarily those associated with common tool operation. This arrangement aims to improve user comfort and control, enabling extended periods of operation while maintaining necessary tool functionality across various working orientations.",
