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.
