Enhancing current safe passing methods, the scalpel features a strengthened temporary lock in the forward position, ensuring the blade remains extended even upon contact with hard surfaces or bone. In the retracted state, the slider mechanism includes a notch that firmly secures the blade. A permanent lock at the back of the scalpel requires deliberate force to engage the slider, ensuring the contaminated blade stays retracted when disposed of in a suitable sharps container after the procedure.
