Application October 15, 1943, Serial No.'506,404 Claims. (01. 51-205) Our invention relates to the conditioning of razor blades, and has among its objects and advantages the provision of an improved blade sharpener.

In the accompanying drawing:

Figure 1 is a view illustrating the manner in which the blade is manipulated edgewise to the sharpener.

Figure 2 is an edge view partly in section.

Figure 3 is a face view, and

Figure 4 is a view of a modified form wherein the handle comprises a solid piece as distinuished from the strap handle of Figures 2 and 3.

In the embodiment of the invention. selected for illustration, we make use of a metal body Ill of platelike contour. This body comprises soft lead, preferably of the type known in the trade as Corroding lead. Lead of this grade has a hardness test of 53.0 (Rockwell B soft metal scale). The body is cut from a sheet rolled from the lead. A thin aluminum coating 12 is applied to the body Ill. One coat of aluminum paint is sprayed on the sheet and on the out surfaces of the body H) to protect the lead from corrosion and to prevent marring of surfaces upon which the sharpener might be placed. This coating also adds to the appearance of the sharpener.

To one edge margin of the body [0 is attached a handle M, which may comprise a strap bent to the shape illustrated and attached by rivets IE to the body. The form of Figure 4 differs only in that the handle I8 is of solid formation and is grooved at to receive an edge margin of the aluminum coated body 22. Rivets 24 fixedly attach the handle to the body.

In operation, the razor blade 26 is engaged edgewise against one end of the body Ill and is pressed lightly into the metal and then pulled endwise. A few such strokes bring the cutting edge to a sharp condition. The sharpener is of relatively simple construction, is easily manufactured at a low cost, in addition to performing an effective sharpening function.

' Without further elaboration, the foregoing will so fully explain our invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

We claim:

1. A blade sharpener comprising a body formed of relatively soft metal, a handle attached to said body, and a protective metallic coating on said body.

2. A razor blade sharpener comprising a lead body, and a thin aluminum coating on said body.

3. A razor blade sharpener comprising a body formed of Corroding lead, a thin aluminum coating on said body to be cut through by a razor blade when engaged edgewise thereagainst, and a handle attached to said body.

4. A blade sharpener comprising a soft metal body having a thin aluminum coating thereon to be engaged by the blade to be sharpened, and a handle therefor.

5. A blade sharpener comprising a rectangular soft metal body having a thin aluminum coating thereon to be engaged by the blade to be sharpened, a handle for the body, formed of strap metal bent to provide an open loop and adjacent superposed edges adapted to be attached: to one of the edges of the body.
