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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
