Abstract: An arm of a variable radius handle of a screw operated lifting mechanism such as a jack has a pivot hub with a universal opening to fit on existing screw drives. The handle on the arm may be slidably adjustable along the arm or the arm itself may be slidably adjustable relative to the pivot point for variable leverage and turning speed.

Abstract: This device gently holds the foreskin of a circumcised penis in a fully extended state, so that the glans may be covered as much as possible with the user's natural skin. The device consists of a shell of silicone rubber in the shape of a truncated cone. Through novel geometry and construction, the device is able to hang on to the user's penis with no adhesive, allowing for convenient and discrete coverage of the glans without the clumsy, bulky, and messy fixtures and techniques associated with other foreskin restoration methods. This covering of skin keeps the glans and inner skin healthy, supple, and sensitive. Also claimed are complementary spacer devices for adding tension to the skin without externally applied force, as well as fixtures for manufacture of the devices.
