Model 92 Corkscrew Keyring
A keyring version of the iconic Cartailler-Deluc Model 92 waiter's friend. The stainless steel body has been miniaturised to easily fit on a belt loop or pocket, and it's delivered with a custom leather pouch for storage.
The screw is nonstick-coated hardened steel, sprung with solid bar steel. There's also a slightly serrated sprung blade for removing foil.
