The SOG-TAC Auto delivers instant blade deployment with premium D2 steel construction and tactical-grade reliability. This automatic folding knife combines a partially serrated tanto point with black titanium nitride coating for enhanced corrosion resistance and reduced friction during cutting tasks.
What Makes This Different
The SOG-TAC Auto features cryo-treated D2 tool steel that maintains its edge 3x longer than standard stainless steel blades. The black TiNi coating provides superior wear resistance while the micro-textured aluminum handle ensures secure grip even in wet conditions. Unlike basic automatic knives, this model incorporates SOG's proven spring-loaded mechanism rated for over 10,000 deployment cycles.
Key Features
- 3.43-inch D2 steel blade with cryo treatment for extended edge retention
- Partially serrated tanto point optimized for piercing and utility cutting
- Black titanium nitride coating resists corrosion and reduces friction
- Micro-textured anodized aluminum handle provides non-slip grip
- Spring-loaded automatic deployment mechanism with safety lock

Field testing demonstrates consistent one-handed operation across temperature ranges from -20°F to 140°F. The D2 steel composition (1.5% carbon, 12% chromium) delivers Rockwell hardness of 60-62 HRC while maintaining chip resistance. Law enforcement and military personnel rely on this blade geometry for rope cutting, package opening, and emergency applications where quick deployment matters.
