Here's another model in my line of EDC keychain retension systems.  These pieces are made from Pure Copper and Brass with brass recessed fillister head screws and hand ground bevels. They are designed to hang securely from any beltloop up to 5/8" wide.  Your Spartan 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 Spartan consists of one core and one scale.  In your cart, please choose LEFT or RIGHT side carry so I can ensure the scale and screws face out!
