The Manticuda VFK has been developed using the best materials, workmanship and treatments possible in a production knife. The knife’s design was developed, tested, and improved over the last seven years to aid in weapon's retention for those who carry a sidearm. All Personal Protective Systems' multi-faceted edge design allows for more cutting angles than standard configured knives. Four separate faces each perform differently acting as macro-serrations. Points (where facets meet) are subjected to a majority of the wear which in turn preserves the integrity of the edge flats.
