I was looking through Etsy and I came across this. It's a bit of a stretch for my budget (as I can't afford to buy anything I wont use right now... I've yet to get into collecting though I can feel it sneaking up on me!)
but I thought this was very unusual:
Ladies Curvfit Vintage Razor
It would seem that the blades themselves are either curved or are flexible enough to curve into the razor!
Has anyone every seen this before or know anything about it?
