The Don by Protech Knives is an full size automatic folder with a distinctive design inspired by traditional Italian folding Stilettos. The Don incorporates Protech's American innovation of the automatic Stiletto featuring modern materials, high tech manufacturing, advanced coil spring mechanism, and quality American production. This version has a black DLC coated 154CM plain edge blade and 3D Ring Pattern, machine contoured Black Hard Anodized aluminum handles.

Brand new directly from Protech Knives, Made in the USA.

Blade: With a nearly 3.5" long blade made of American 154cm stainless steel, the Don has plenty of cutting edge for utility tasks. A nearly full length swedge makes for an exceptionally fine point that gives this knife some of the highest levels of piercing performance around and classic stiletto styling when paired with the curving dual guards. The blade has a durable and corrosion resistant black DLC (Diamond Like Carbon) coating that is non-reflective for discreet use. The blade deploys via a button operated coil spring mechanism that is fast and smooth giving you quick access when the seconds count. 

Handle: A contoured, coffin-shaped handle made of 6061-T6 Hard Anodized aluminum provides a comfortable in-hand feel in a variety of grips and deploys smoothly from the pocket for use. 3D concentric rings milled into the handle offer added traction and visual appeal. Black hardware and button lock finish off this elegant tactical automatic.

Carries via a right hand tip-up DLC deep carry pocket clip.

Comes with a velvet lined snap lid display and storage box.

Crucible 154cm: An improved version of 440C with added molybdenum, 154cm offers improved corrosion resistance and edge retention, as well as a higher level wear resistance.
