Extrema Ratio ANT Black Stone Washed M390
The ANT is the most compact of the Extrema Ratio folding knives, with an extremely robust and reliable structure despite its small size. This Black Stone Washed M390 version uses Böhler M390 powder-metallurgy steel hardened to 61 HRC for cutting efficiency and resistance to wear and oxidation. Extrema Ratio has worked with the Austrian maker Böhler for more than 20 years.
The handle combines anodised Anticorodal aluminium with a hardened steel frame that provides the lock (frame lock). The sheepfoot blade, with a small opening slot, has a straight spine on which the fingers rest comfortably.
