This was an easy prop to make. All you need is a women's Gillette disposable razor.
They come in a number of colors, it really doesn't matter which one you get. I bought 2 and spraypainted them black. The details I scratchbuilt from plasticard.I glued a universal swivel clip to the back so I could clip them to my belt. A quick clear coat to seal them and they're done.
