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: A combination tool includes a tool head having a jaw mechanism with two jaws lying in a tool head plane. A first handle is pivotably attached to the jaw mechanism and rotatable in a first direction about a first pivot axle lying in the tool head plane, between a nested position wherein the first handle lies coplanar with and adjacent to the jaw mechanism and a deployed position wherein the first handle is coplanar with and remote from the jaw mechanism. A second handle is pivotably attached to the jaw mechanism and rotatable in a second direction, opposite to the first direction, about a second pivot axle lying in the tool head plane, between a nested position wherein the second handle lies coplanar with and adjacent to the jaw mechanism and a deployed position wherein the second handle is coplanar with and remote from the jaw mechanism.
