A disposable safety rotary rotary razor comprising: A. an elongated semi-rigid outer cylindrical sleeve open at both ends and having an open slot extending axially throughout the length of said sleeve, B. a handle fixed to the midpoint of said sleeve and extending at right angle thereto, C. an elongated hexagonal spool disposed within said sleeve and manually rotatable therein on an axis parallel to the wall of said sleeve, said spool having in cross section the shape of a hexagon with each of its six flat faces extending the entire length of said spool, D. six separate stainless steel shaving blades, each of said blades being fixed to one of the flat faces of said elongated spool extending throughout the length thereof and each of said shaving blades having a cutting edge protruding outwardly from said spool extending beyond the flat faces to which each blade is fixed, E. each of said six blades being rotatable with said spool and means to index each of said blades opposite the open slot of said elongated semi-rigid outer cylindrical sleeve and the cutting edge of each blade adapted to protrude outwardly through said slot, F. an axially extending bore formed in said elongated hexagonal spool and a control knob for each end of said spool, each control knob having a pin adapted to enter said bore in a manner to fix said control knobs to opposite ends of said spool and manually rotate said spool, G. a semi-flexible cylindrical shaped shim adapted to be fitted within said semi-riged outer cylindrical sleeve and to surround said elongated hexagonal spool which is disposed within said sleeve whereby both said shim and said spool are disposed within said semi-rigid outer cylinder, said shim being adhesed to the inner wall of said outer cylinder and said spool being rotatable within both said shim and said outer cylinder, H. an open slot formed in said cylindrically shaped semiflexible shim said slot extending parallel to the open slot of the semi-rigid outer cylindrical sleeve in which it is disposed and to which it is adhesed said slot having inwardly turned edges along the length of the slot to form blade wiper reeds and arranged to press inwardly against and contact the blades as they are rotated and moved out of shaving position.
