I'll parrot what the others have suggested. Offering to have a man shave your legs or private areas would be hot for a man. If you trust him to do that! I'm sure that the vast majority would be very careful.
I'm not too fond of the straight edged razor but I AM fond of the idea of a leather strop to spank! It could be a good prop if nothing else!

There are a few sites out there. This looked like a nice one. "Menacing" someone with a straight razor might be interesting.
Great topic!!!
