William Henry Montana Pocketknife 2.5" Blade. The Knife features a frame sculpted from solid billets of aircraft-grade aluminum, deeply knurled for a safe & steady grip — then hard anodized to military-grade specs. The drop-point blade swings open & locks into position with a positive 'click'. Storied D2 German steel is tempered to HRC 60-61 to permit holding an exacting, razor edge. Lastly, each Montana receives a custom inlay of carbon fiber, exotic cocobolo, or rare box elder burl wood.
