Pro-Tech TR-3 Auto Sapphire

The Pro-Tech TR-3 Auto Sapphire is a high-performance automatic folder that combines rugged tactical capability with bold, eye-catching style. Built on Pro-Tech’s proven Tactical Response 3 platform, this knife delivers the fast deployment, dependable construction, and premium American craftsmanship that have made the TR-3 one of the company’s most respected automatic models. With its striking sapphire blue blade finish and rugged black aluminum handle, the TR-3 Auto Sapphire stands out as both a serious working knife and a standout collector piece.

At the center of the knife is a 3.5" 154CM stainless steel drop point blade featuring a vivid sapphire blue finish. Known for its excellent balance of edge retention, corrosion resistance, and toughness, 154CM remains a trusted blade steel for premium automatic knives. The drop point blade profile offers versatile cutting capability with excellent slicing performance, dependable tip strength, and precise control for a wide range of everyday and tactical cutting tasks. Whether handling utility work, outdoor use, or daily carry duties, the TR-3’s blade is built to perform with confidence.

The sapphire blue finish gives the blade a unique, high-contrast appearance that immediately sets this knife apart from standard tactical folders. Bold without being excessive, the finish adds visual depth and custom-style appeal while complementing the rugged black handle. It creates a striking modern look that blends performance-driven design with standout aesthetics.

Deployment is fast and authoritative thanks to Pro-Tech’s renowned automatic push-button mechanism. With a quick press of the button, the blade fires open instantly and locks securely into place with the crisp, reliable action Pro-Tech automatics are known for. The out-the-side automatic design allows for rapid one-handed operation while maintaining smooth deployment and dependable lockup through repeated daily use.

The handle is crafted from black aluminum, offering lightweight durability and a comfortable, ergonomic grip. Strong enough for hard-use applications while remaining easy to carry, the aluminum frame keeps the knife balanced and responsive in hand. The black finish pairs perfectly with the sapphire blade, creating a sleek tactical appearance with just the right amount of aggressive styling.

A tip-up pocket clip keeps the knife secure, discreet, and ready for fast access throughout the day. At 4.5" closed and 8" overall, the TR-3 offers a full-sized working platform while still maintaining practical everyday carry dimensions. Its balanced proportions and durable construction make it equally suited for professional use, outdoor carry, or serious EDC rotation.

Proudly made in the USA, the Pro-Tech TR-3 Auto Sapphire delivers premium materials, precision engineering, and bold styling in a proven automatic platform built for dependable real-world performance.
