ABSTRACT:
A knife or tool (10) comprising a member (11) with a blade (12) and tool element (14) thereon, pivotable at (40) whereby one or the other, blade (12) or tool element (14), is correspondingly disposed in a sheath (22) while the other is exposed. Scales (16, 17) are mounted to each side (20, 21) of the member (11) and encompassed within its sheath (22), while an urging means (54, 55) or spring mechanisms are mounted between the member (11) at its pivot point (40) and the scales (16, 17). In the pivoting motion, studs (65), of pairs of studs (65, 66) correspondingly mounted on both sides (20, 21) of the member (11) at particular points, are caused to be released from their bayonet slots (62) in the scales (16, 17) against the prejudicing action of the spring mechanisms (54, 55) which nevertheless yield as a third pair of studs (72) simultaneously released from open-ended slots (68) in the frontal ends of their scales (16, 17) move the member's pivoting action along camming surfaces (73) on the frontal ends of the scales (16, 17). The third pair of studs (72) are received in another set of open-ended slots (69) on the scales' frontal ends. The second pair of studs (66) correspondingly mounted on both sides (20, 21) of the member (11) at another particular point also reach another set of bayonet slots (62) in the scales (16, 17) to be retained therein by such prejudicing action. A clip member (36) is mounted to either side of the sheath (22), depending upon the user's desires. The tool element (14) itself is an additional tool, such as a can opener (78), screw driver, etc., thus making the assembly of elements adaptable as well to other tools in addition to knives.
