Abstract: A hand tool such as a knife or a combination tool includes multiple blades, each independently rotatable on a common axle between a closed position within a handle of the tool and an open position extending from the handle. Each blade is positively but releasably locked into its open position. Those blades which remain closed are biased toward the closed position when the opened blade is locked into position and also as it is opened and closed. A single locking, releasing, and biasing mechanism serves all of the blades in one handle.

Abstract: An anti-shock structure of a hammer handle comprises a main rod, a handle sleeve, an elastic element, and a plug. A longitudinal storing slot is disposed inside the handle sleeve. The elastic element is disposed in the longitudinal storing slot. One end of the elastic element has a U-shaped portion. The elastic element's cross-sectional width is less than the longitudinal storing slot's cross-sectional width. So, during the swinging movement before knocking, the U-shaped portion of the elastic element will resist the reactive force so as to ensure the excellent holding effect. After the knocking, an opened portion of the elastic element will absorb the shock. That is, both excellent holding effect and the anti-shock function are achieved.
