This small but clever device is a vintage Siemens razor blade sharpener, dating back to a time when people repaired, reused, and carefully maintained everyday items instead of throwing them away.
Found inside a house built in 1914, this sharpener offers a fascinating glimpse into the past, when shaving was more of a daily ritual and quality grooming tools were meant to last.
The device is compact and comes in a small case, with a noticeable red cord attached. Inside are two brass pins that spin when the cord is pulled. That motion would move a mounted razor blade back and forth against sharpening surfaces, gently honing the blade’s edges.

Instead of replacing blades constantly, people used tools like this to extend the life of reusable razor blades. For many households, it was a practical and money-saving invention—small in size, but very smart in design.
