Keychain with titanium “Dot the i" BB&F / 3DP Design ferrule.   Keychain element is milled from 303 stainless steel.   Base piece is CNC milled from aluminum.

This piece is a screw-in assembly but will be bonded together to prevent it from coming loose in your pocket.  It can be left unbonded on request to allow you to change the ferrule - just drop us a note to let us know your preference.
