Apparatus for sharpening and or honing a multi-bladed razor cartridge including a sharpening member, a housing to secure the sharpening member. The method involves setting as a primary goal to be proved an attribute delegation from a trusted principal to the subject and then seeking a backwards proof of the primary goal by a process of recursively taking a goal to be proved, starting with the primary goal, and decomposing it into subgoals one of which corresponds to an attribute delegation already proved by an available certificate. It is preferably implanted by the severance of an included electrolytically severable joint. For the various embodiments, the composition of the present disclosure can also include an aprotic solvent, such as a ketone. A release device is interengaged between the housing and the enclosure, and is selectively movable between a first position, locking the enclosure in the mounting condition, and a second position, releasing the enclosure from the mounting condition to the removal condition and disconnecting the second electrical connector from the first electrical connector.
