The Pro Tech Tactical Response 4 brings full-size automatic performance to a rugged, purpose-built design that’s ready for serious everyday use. Built around a solid green 6061 aluminum handle, this TR-4 delivers a confident combination of strength, durability, and unmistakable Pro-Tech styling. The solid handle texture keeps the profile clean while providing a secure grip, and the blasted hardware complements the knife’s hard-working aesthetic.
At the heart of the TR-4 is a 4.00-inch drop point blade crafted from MagnaMax steel and finished with a rugged stonewash. The versatile drop point profile provides a strong, practical point and a substantial cutting edge, while the stonewashed finish helps conceal the marks that naturally come with hard use. When you need the blade, the button-operated automatic action deploys it quickly and decisively.
A steel secondary safety switch adds another layer of control, helping prevent unintended deployment when the knife is carried or stored. The TR-4 also features an integrated glass breaker, giving this full-size automatic an added measure of utility when circumstances demand more than a cutting tool.
The 5.25-inch handle gives the TR-4 a substantial feel in hand, while the 9.25-inch overall length puts it firmly in the full-size category. Despite its capable dimensions, the knife weighs a manageable 5.30 ounces, making it substantial without feeling unnecessarily heavy. The long blasted deep-carry clip is designed for right-handed carry and helps keep the knife riding securely and discreetly in the pocket.
From its green aluminum handle and stonewashed MagnaMax blade to its steel safety switch and glass breaker, the Tactical Response 4 is built with a rugged, professional mindset. It’s a hard-use automatic that combines dependable construction, fast deployment, and practical features in one formidable package.
