Pro-Tech Knives Runt J4 Auto Tanto Tuxedo Handle AUPT5452

The Pro-Tech Knives Runt J4 Auto Tanto Tuxedo Handle delivers premium automatic performance in a compact package with unmistakable style and refined detailing. Built on Pro-Tech’s highly respected Runt platform, this knife combines fast automatic deployment, durable American-made construction, and elegant tuxedo-inspired aesthetics into one highly capable everyday carry folder. Compact enough for effortless pocket carry yet rugged enough for serious daily use, the Runt J4 stands out as both a dependable tool and a striking collector piece.

The knife features a 2" 154CM stainless steel tanto blade with a black anodized finish. Known for its excellent combination of toughness, edge retention, and corrosion resistance, 154CM remains a trusted steel for high-performance production knives. The tanto blade profile provides reinforced tip strength and aggressive piercing capability while still offering reliable slicing performance for everyday cutting tasks. Its compact size makes it ideal for opening packages, utility work, and quick daily cutting needs while maintaining excellent control and maneuverability.

The black anodized blade finish gives the knife a sleek tactical appearance while helping reduce glare and hide wear from regular use. The dark blade pairs perfectly with the tuxedo-themed handle, creating a clean, high-contrast look that feels both refined and purpose-built.

Deployment comes through Pro-Tech’s renowned automatic push-button mechanism. With a simple press of the button, the blade fires open quickly and locks firmly into place with the crisp, authoritative action Pro-Tech automatics are famous for. The mechanism delivers fast one-handed access while maintaining dependable lockup and smooth operation throughout repeated daily use.

The standout feature of this Runt J4 is its tuxedo-inspired handle design. Black anodized aluminum handles are paired with polished ivory micarta inlays, creating a bold contrast that gives the knife an upscale custom appearance. The aluminum frame keeps the knife lightweight and durable, while the smooth micarta inlays add warmth, texture, and visual sophistication. Despite its refined styling, the handle remains rugged enough for everyday carry and practical use.

A tip-down pocket clip keeps the knife secure and accessible throughout the day while maintaining a slim carry profile. At 3.33" closed and 5.25" overall, the Runt J4 is compact enough to disappear in pocket while still offering the fast deployment and solid cutting performance expected from a premium automatic knife.

Proudly made in the USA, the Pro-Tech Runt J4 Auto Tanto Tuxedo Handle combines precision engineering, premium materials, and standout styling into a compact automatic folder built for both performance and presentation.
