Abstract
A retractable safety knife has a hollow handle with an opening at an end thereof, a pusher that is movably disposed within the handle and is operable by a user, and a blade that is connected with an end of the pusher. When the pusher moves from a blade-retracted position to a blade-extended position, the blade extends outwardly from the handle opening and rotates from a nested position to an extended position.
