The Pro-Tech Large Don 1921-MOP Automatic Knife is a commanding, full-size automatic that merges classic Italian stiletto styling with modern American precision. As one of the largest knives in Pro-Tech’s lineup, the Large Don delivers bold presence, premium materials, and powerful performance.

At its center is a massive 4.5-inch spear point blade crafted from 154CM stainless steel, finished in a clean satin polish. This combination offers excellent edge retention, corrosion resistance, and a refined look that highlights the blade’s symmetrical profile and grind.

The handle is made from black anodized aluminum, shaped with smooth, elegant lines that echo traditional stiletto design. Elevating the knife’s luxury appeal is the Mother of Pearl (MOP) push-button, a standout feature that adds sophistication and collectible value.
