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.

The present invention provides a power-assisted folding knife, comprising a handle, a blade, a locking mechanism, an assisting mechanism and a second assisting mechanism. The blade is rotatably connected to the handle. The locking mechanism and the second assisting mechanism are provided inside the handle. The assisting mechanism is connected to the handle and the blade respectively. When the blade is in a folded position, the assisting mechanism and the second assisting mechanism are used for locking or unlocking the blade. When the blade is in an unfolded position, the locking mechanism is used for locking or unlocking the blade. When the power-assisted folding knife is unfolded, the assisting mechanism and the second assisting mechanism provide assisting force for the blade and/or the handle.
