Yesterday I showed you a small handheld gadget with a pull-out crank and challenged you to guess what it was. This object is a stropper (sharpener) for Gillette-style safety razor blades, produced by the TwinPlex Stamping Company of Chicago, Illinois in the 1920s.

Congratulations to all those who guessed correctly, and stay tuned for the next Mystery Object video!
