Bring a knife to a gunfight! 

Lewis Leathers has brought us this striking mini pen-knife keyring. A bullet casing that features a small blade easily flippable inside, this piece is inspired by vintage WW2 historical designs. 

The shell is made from cast brass while the knife is made from polished stainless steel.

This keyring is perfect for a range of outdoor activities like camping, fishing or hiking!

Just don't take it on your flight!
