Tiny Folding Knife with Keyring

From Opinel:

The No.02 is our smallest folding knife (since the discontinuation of the No.01 in the 1930's). Small in stature, but highly efficient, the keychain version of the No.02 follows you everywhere. This tiny knife is excellent for small tasks like opening letters or cutting papers. This is a very small knife (under 2 inches when folded!)

Hand wash only. Do not immerse your knife in water, as this could warp the wooden handle. Dry the blade before closing. 

Opinel is a company based in France, founded in 1890.
