Abstract: The invention relates to cutters, and provides a cutter comprising a base and a cutting-blade carrying arm. The base and the arm may be parts of a one-piece plastic molding which incorporates a connection between the base and the arm, which connection permits movement of the arm relative to the base during the cutting action. The arm may carry at least one flexible member which engages the material to be cut prior to engagement of the material by the cutting blade, whereby the material is restrained from movement during the cutting action.

Abstract: A hand tool, such as a pruner, has two pivotally movable members which are biassed apart by a helical spring disposed in a slot in one of the members, the slot being arcuate about the pivotal axis of the members. One end of the spring abuts one end of the slot and the other end of the spring is engaged by a pin which projects into the slot from the other member.

Abstract: A hand tool, such as a pruner, has two pivotally movable members which are biassed open by a spring. A catch, for locking the tool in the closed position, is fitted into a non-circular aperture in a part of one of the members which overlaps the other member, the shank of the catch being undercut to allow the catch to rotate in the aperture, but prevent its withdrawal from the aperture except in the rotational position in which it was inserted into the aperture. A detent is provided, for rotation by the catch to engage and lock the members together. The member containing the catch is so shaped that the detent can be fitted to or withdrawn from the catch only in a position in which the shank of the catch is locked in the member. Consequently, so long as the detent remains in position in the catch, the catch cannot be removed.
