SHOP CASE KNIVESThe Pro-Tech TR-3 Integrity Thumbstud Manual Folder is a full-size, precision-engineered folding knife designed for users who demand performance, durability, and confidence in a sleek, modern package. Part of Pro-Tech’s Integrity series, this TR-3 model combines premium materials, refined geometry, and thoughtful ergonomics to create a tool that excels in everyday carry, field use, and professional applications alike. Every detail, from the blade profile to the textured handle, is crafted for function, control, and consistent operation.
The heart of the TR-3 Integrity is a 3.5-inch spear point blade made from MagnaCut steel. Recognized for its exceptional edge retention, toughness, and corrosion resistance, MagnaCut offers dependable performance across a wide range of tasks. The spear point profile provides a strong, versatile tip while maintaining a long, straight cutting edge for precise slicing, piercing, and controlled utility work. A DLC black finish protects the steel from wear and corrosion while giving the blade a refined, tactical look. The 0.12-inch-thick blade strikes a balance between durability and control, delivering authority when needed without feeling cumbersome.
The manual thumbstud deployment is fast, smooth, and intuitive, complemented by a blasted button lock for secure engagement and confident one-handed operation. This combination allows users to deploy and lock the blade quickly while maintaining precise control at all times. The TR-3 design prioritizes ergonomic comfort and ease of use, making extended carry and repeated deployment effortless.
The handle is machined from 6061 aluminum with a relic-style black texture that provides a tactile, secure grip while adding a distinctive visual character. Measuring 4.6 inches, the handle offers a full-size feel in the hand without excess bulk, and the wide deep-carry pocket clip keeps the knife discreet while ensuring it remains quickly accessible. Blasted hardware complements the overall aesthetic, maintaining a cohesive, professional appearance.
Weighing 3.8 ounces and extending to an overall length of 8 inches, the TR-3 Integrity is substantial enough to inspire confidence in demanding tasks while remaining manageable for everyday carry. Built in the USA with Pro-Tech’s signature precision and attention to detail, this folding knife delivers a combination of premium materials, smooth mechanics, and thoughtful design that users can rely on every day.
