Spey Knife (Speying Knife)

A veterinary knife, with one spey blade and one long (2″ or so), thin tang that terminates in a short turned-down portion which is sharpened on the inside; used to convert roosters to capons. For sterilization purposes, the handles are usually made of metal. Small ones with upturned handles (as pictured) are commonly called “Rooster Nutters”.
