The Marfione custom Juggernaut was a father & son collaboration between Anthony Marfione and Sean Marfione. This massive fixed blade (14.5" overall length") was the second fixed blade design from Sean after The Apex. The Juggernaut pioneered some of the design traits we would see take hold over time, including the top spine having extremely stylized jimping paired with the holes in the blade giving a very straight razor adjacent look. 

Seans designs grew over time to include these two features throughout; including the Warhound Folder and all of the OTF blades he would design (Hellhound Tanto, Hellhound Straight Razor, Warhound Wharncliffe) There were only a small handful of these ever produced and are considered Very Rare
