Abstract: A scissors, preferably for use as one of the elements in a pocket knife such as a jackknife, which is biased to an open position by a concealed spring. The scissors includes two rectilinear blades which are pivotally secured to each other by a pivot at a point intermediate the ends of the blades. The blades are biased to open position in which the blades are at an acute angle to each other by the spring, which is mounted about the pivot. The spring includes a single flat coil which spans an arc of less than 360.degree., typically 270.degree.. One end of the coil has an integral leg perpendicular to the plane of the coil and parallel to and adjacent the pivot. The other end of the coil extends tangentially away from the arc of the spring coil. One of the blades has a pocket, including an extension, adjacent the pivot. The other blade also has a pocket adjacent the pivot, and the leg is located in this pocket. The spring is disposed in the pockets with the coil of the spring extending about the pivot.

Abstract: A folding knife featuring a locking sleeve at the junction between the blade and handle, so that the knife blade may be locked in both the open and closed positions. The locking sleeve has an enlargement which accommodates the end of the blade adjacent the tang, so that the locking sleeve may be partially rotated when the knife is closed and at least the sharp edge portion of the blade is within a recess in the handle, whereby the blade is restrained from egress from the handle. Suitable structure is provided to prevent axial sliding movement of the locking sleeve off of the end of the handle.

Abstract: An implement rack having upper and lower slotted members mounted on a support. The slots are so shaped and disposed as to receive, from the front of the rack, knife blades at off-vertical angles, the knives then resting on the upper member at the bases of their handles and swinging toward vertical positions. Tongues between the members prevent the blades from being withdrawn forwardly from the rack in their vertical or more nearly vertical positions. Such operation of the rack is predicated upon the utilization of knives having their centers of gravity in the blades. The rack also can be used for culinary utensils. The invention further encompasses a unique method of inserting such knives and implements into the rack, of retaining the knives within the rack in a manner which reduces the likelihood of accidental release, and of permitting convenient removal of the knives from the rack. This invention is intended for use as a fixture to be affixed to a vertical surface.
