Marfione Custom Knives has created a stunning adaptation of the Ultratech Spartan with this prize-worthy piece. It has a bearing grade brass chassis and ringed brass hardware. The double-edge Gladius Tip blade is hand ground, mirror polished Elmax steel. Direct from maker with certificate of authenticity. Microtech has updated the venerable Ultratech knife. While the dimensions and action remain the same as the previous model, this latest version features beveled edges, a modified thumb slide and tri-angle hardware. The end result is an impressive Ultratech that improves upon what has become the must-have OTF automatic.
