SOG TAC XR Folding Knife 3.39" D2 Steel OD Green G10 Handle

The SOG TAC XR folding knife delivers premium cutting performance with its 3.39-inch D2 steel blade and tactical-grade construction. This knife combines advanced metallurgy with ergonomic design for professionals who demand reliability in demanding environments.

What Makes This Different

The TAC XR features a cryogenically treated D2 steel blade with black titanium nitride coating, providing superior edge retention compared to standard stainless steel alternatives. The cryo treatment refines the steel's grain structure, resulting in a blade that maintains sharpness 40% longer than conventional heat-treated steel. Combined with the TiNi coating's corrosion resistance and reduced friction properties, this knife outperforms traditional folding knives in both durability and cutting efficiency.

Key Features

• 3.39-inch D2 steel blade with cryogenic treatment for extended edge retention
• Black titanium nitride coating resists corrosion and reduces cutting friction
• OD Green G10 handle scales provide superior grip in wet conditions
• Clip point blade geometry optimizes piercing and precision cutting tasks
• Ambidextrous pocket clip allows tip-up or tip-down carry configurations
• Liner lock mechanism ensures secure blade lockup during use
• Overall length of 8.2 inches when open, 4.81 inches closed

Field testing demonstrates the TAC XR's versatility across multiple applications, from tactical operations to outdoor recreation. The D2 steel composition (1.5% carbon, 12% chromium) provides the hardness necessary for demanding cutting tasks while maintaining sufficient toughness to prevent chipping. The G10 handle material withstands temperature extremes from -40°F to 200°F without degradation, making this knife reliable in diverse environmental conditions.
