A knife includes interchangeable blades that are secured within the handle using a locking mechanism having a lock pin disposed between the distal end of the lock bar and the blade. In addition to strengthening the lock, the lock pin also serves as a safety catch n the unlikely event of lock failure, resisting rotation of the blade into a position in which the user's fingers would be cut.
