In addition to running Microtech Knives, Tony also creates beautiful custom versions of various Microtech production styles, which are known as Marfione Custom Knives. These knives not only offer the quality of Microtech, but are hand ground by Tony himself, extremely limited and often times have custom refinements designed and applied by Tony. Such pieces are highly sought after by collectors and are destined to appreciate in value due to their unique features and limited quantities.
