Here's another model in my line of EDC keychain retension systems.  These pieces are made from Pure Brass with brass truss head screws and hand ground bevels. They are designed to hang securely from any beltloop up to 5/8" wide.  Your Falcon comes as pictured, with 3 brass split rings.  The mushroom shaped void makes it very hard for these to come loose unless you hook your thumb under the belt loop and lift a little before removing.  You'll be good at it in no time!
 
The Falcon consists of one core and one scale.
