Up for sale is a remarkably well-preserved, complete 1917 mechanical safety razor blade sharpener (stropper) kit.

The back plate of the metal casing is clearly stamped with historical authenticity: "PROTECTED AT PATENT OFFICE - PATENT No. 110488" (registered in 1917).

Manufactured in the United Kingdom during the World War I era, this fascinating piece of engineering features an automated twin-roller system designed to extend the life of early safety razor blades.

**Kit Completeness & Condition:**
This is an exceptionally rare find for collectors because the kit is 100% complete with all its original components, which are usually lost over the decades:
* **The Sharpener Unit:** The internal twin-roller mechanical unit is intact, featuring its original dark composition rollers and central metal blade-holding bracket.
* **The Hand Crank:** Includes the original, detachable metal winding handle that slots perfectly onto the side drive gear.
* **The Honing Compound:** Tucked into the corner is the original, small reddish-brown dressing/honing block used to prime the rollers.
* **The Paperwork:** Comes with the original, aged paper "DIRECTIONS" instruction sheet detailing operating and oiling care.
* **The Box:** Everything is housed inside its original deep maroon presentation box.

**Cosmetic Condition:**
The metal casing shows a beautiful, authentic aged patina with light surface oxidation consistent with a 100+ year-old item. The internal gearing is intact. The paper instructions show natural yellowing and fraying at the edges but remain fully legible. Please review the photos carefully to verify the exact cosmetic state of this antique.
**Perfect For:**
* Antique shaving and barber shop memorabilia collectors.
* World War I era history enthusiasts.
* Historical theatre, film, or television prop departments.
* Unique rustic industrial decor for displays or shelving.

**Shipping:**
Will be securely wrapped in heavy bubble wrap and boxed to protect the delicate internal mechanics and original paper elements during transit.
