The IMDB entry says that the razor was a rubber prop, and indeed, it had no visible markings. But the model was good. Probably about 5/8, half-hollow, round point, three-pin scales. I know little about modern production razors, but it seemed pretty Dovo-ish, if Dovo made any half-hollow blades (do they?). I'm guessing it was as thick as it was so it wouldn't bend onscreen. She really used it to scrape off lather. And I agree, the technique looked uncommonly good!
