Ferruled keychain / single prong pitch tool, sold without a ferrule (because you already have the ferrule you want to use it with).  

This product is an assembly.  It screws together and allows you to change the ferrule or change from a keychain to a single prong pitch tool.   (We recommend bonding it together with a drop of super glue on the screw so it won't come unscrewed in your pocket.)  Comes with a lasered GTi fob.  Fits both shorty (1") and standard (1.3") ferrules.  

Keychain and single prong elements are stainless steel.
