This is a Serial numbered Marfione Custom UTX-85 beard comb. Personally made by Anthony Marfione and Sean Marfione.
The blade is a comb blade in Elmax and fully deploys just like a Microtech OTF. This beard comb also includes The Real McCoy Beard Oil.
UTX-85's are a double action knife which means that the blade deploys when pushing forward on the lever and retracts when pulling back.
