Abstract: An out-the-front knife, components thereof, and associated methods. The out-the front knife can be a double-action spring-assisted knife. The knife includes a handle and a blade. The handle includes a rear end and a front opening opposite the rear end. The blade is movable with respect to the handle between stowed and deployed positions. In the stowed position, the blade is biased rearward. The knife includes an actuator movable in a deploying direction to spring the blade forward away from the stowed position toward the deployed position.

Abstract: A cutter tool that includes a shank by which the tool is releasably retainable within a tool holder, an enlarged shoulder or heel provided at one end of the shank and adapted, in use, to abut a seating surface of a tool holder and limit the penetration of the tool holder into a receiving aperture of the tool holder, and an integral blade provided beyond the enlarged shoulder or heel and terminating in a carbide or other tip. The tool is provided with a zone of weakness such that if subjected to fracture forces, a fracture will be encouraged to propagate from the zone of weakness in a particular desired manner.

Abstract: A mineral cutter pick (1) has an oblong section to define leading (3), trailing (4) and side (5) faces of a shank (2), and has longitudinal and transverse axes (6, 7). The shank (2) is provided with a single, circular section through hole (16) extending orthogonally across its side faces (5), in which hole (16) is fitted a resilient member (17) of circular section with an external diameter to match that of the hole (16), the resilient member (17) itself having a coaxial through hole (18) so as to provide an annulus of constant thickness when uncompressed and adapted, in use, after the pick shank (2) has been inserted into a shank-receiving aperture (22) of a pick box (5), to itself receive, and frictionally retain, a manually insertable, and manually removable, metal pin (23) adapted to project beyond the side faces (5).
