The Pro-Tech Large Don 1921-LTD Automatic Knife is an imposing, high-end automatic that blends classic Italian stiletto inspiration with modern American precision. As one of the largest production automatics from Pro-Tech, the “Don” lives up to its name—delivering commanding presence, premium materials, and exceptional performance.

The handle is crafted from black anodized aluminum, sculpted with smooth, flowing lines that echo traditional stiletto styling. Adding a touch of luxury, this limited model features a Mother of Pearl (MOP) push-button, elevating both aesthetics and collectibility.
