Yup, it's a Rolls Razor. They are actually pretty common to see (though in that shape they are not common - that is an excellent example), though I don't know how common their use is. They are single edge's what can be honed and stropped - some call them a straight on a stick, but I think SE is more accurate.

If I'm not mistaken, Stimpy has one and really likes it. Maybe he'll chime in.
