Pro-Tech Knives Runt J4 Auto Tanto Blue Handle AUPT5415BLUE

The Pro-Tech Knives Runt J4 Auto Tanto Blue Handle is a compact automatic folder built for fast deployment, rugged cutting performance, and lightweight everyday carry convenience. Small in size but serious in capability, the Runt series has become one of Pro-Tech’s most popular compact automatics thanks to its precision construction, reliable action, and highly practical carry profile. This version combines a tough tanto blade with bold blue aluminum scales for a knife that stands out visually while remaining built for real-world use.

The 2" 154CM stainless steel blade features a durable black finish and an aggressive tanto profile designed for strength and precision. Known for its excellent balance of toughness, corrosion resistance, and edge retention, 154CM is a trusted steel that performs exceptionally well in everyday carry applications. The tanto blade shape offers reinforced tip strength and excellent piercing capability while maintaining reliable slicing performance for utility work, package opening, cord cutting, and other daily tasks. Its compact size makes it especially practical for discreet carry and quick-access cutting jobs.

The black blade finish gives the knife a rugged tactical appearance while helping reduce glare and conceal wear from regular use. Combined with the angular tanto grind, the blade gives the Runt J4 a bold, purposeful look that matches its fast automatic action.

Deployment comes through Pro-Tech’s proven automatic push-button mechanism. With a quick press of the button, the blade fires open smoothly and locks firmly into place with the crisp, authoritative action Pro-Tech automatics are known for. The out-the-side automatic design provides fast one-handed operation and dependable lockup in a highly compact platform.

The blue aluminum handle keeps the knife lightweight while offering solid durability and comfortable handling. The anodized finish adds vibrant color without sacrificing the rugged construction expected from a hard-use everyday carry knife. Ergonomically shaped for secure grip and control, the handle feels substantial despite the knife’s compact footprint, making it comfortable and confidence-inspiring during use.

A tip-down pocket clip supports right-hand carry and keeps the knife secure, discreet, and ready for quick deployment throughout the day. At just 3.33" closed, 5.25" overall, and weighing only 2.10 ounces, the Runt J4 disappears easily into pocket while still delivering the fast deployment and cutting capability expected from a premium automatic knife.

Proudly made in the USA, the Pro-Tech Runt J4 Auto Tanto combines premium materials, compact portability, and dependable automatic performance into a rugged everyday carry package built for serious users.
