Abstract: A straight knife is disclosed including an interchangeable, pivoting double-ended blade and having a locking member within a handle. A pivot member is inserted through a blade body section to allow pivoting of either blade end to an operative position extended from a blade channel defined by the handle. The locking member is positioned adjacent the blade body section within the blade channel and is composed of a resilient spring material. Upon single-handed manipulation by the user, the locking member is moved from an engaged and locked position to a disengaged position apart from the blade for pivoting of the blade to expose either blade end to an operative position. The blade is removable from the handle upon removal of the pivot member and manipulation of the locking member for inserting another like-configured pivotable blade in the blade channel for single-handedly pivoting the blade to exposed a selected blade end.

Abstract: A straight knife with an interchangeable, pivoting double-ended blade. The knife includes a handle forming a blade channel in which the unused end of the blade is stored. A pivot pin and a locking pin are provided for engaging a pair of through-openings in both the handle and the blade to allow the blade to be secured in an operative position. The pivot pin and the locking pin are connected to a gripping member by a linkage. The gripping member is provided to allow the pins to be quickly and easily removed using one hand, even when wearing bulky gloves. A locking mechanism on each of the pivot pin and the locking pin engages the handle to secure the pins in the handle. The lock pin is be removed to allow rotation of the blade around the pivot pin. Both the lock pin and the pivot pin are removed to exchange one blade for another.
