Razor blade handle designed to allow the use of both sides of the blade (they seem to last longer that way). Uses standard 1.5" razor blades*.
There are two versions of the design. The stainless steel blades* I have are thinner than the cheaper blades linked above. The two designs only differ by about a quarter of a millimeter.
More of my tool designs can be found here.
