Abstract: A spare blade storage case for barbers' razors of the type which hold replaceable blades. The spare blades are held laterally in the case which allows the blades to be taken out from the case by a direct upwardly motion. There are provided storage spaces for individual spare blades, each of the storage spaces being defined by a pair of sidewalls which rise from a bottom of the case and are yieldable away from the spare blade as this spare blade is inserted into this space. The sidewalls are provided on their inner surfaces with projections engageable with upper sides of ridges formed on both sides of each spare blade. One end wall of the case is opened so as to expose at least one end portion of the spare blades extending above the ridges thereof.

Abstract: A blade for a blade exchangeable razor is provided which realizes easy use and smooth haircutting. The razor is adapted to exchangeably support a blade by a blade holder. The blade comprises a thin blade portion having an edge and a back support including side plates for supporting the thin blade portion therebetween and a pair of protrusions formed on the side plates in the longitudinal direction thereof at positions of the side plates close to lower ends of the blade holder. Since the pair of protrusions on the side plates of the back support are located proximal to the lower ends of the blade holder, hair cut by the edge moves away from the blade holder by the action of the protrusions, thereby preventing the cut hair from entering between the back support and the blade holder.

Abstract: Herein disclosed is a T-shaped razor comprising a holder, and a head attached to the holder and having at least one blade.
