SOG-TAC Auto Tanto Folding Knife 3.43" D2 Steel Black TiNi

The SOG-TAC Auto delivers instant blade deployment with premium D2 tool steel construction and tactical tanto geometry. This automatic folding knife combines SOG's proven spring mechanism with a black TiNi cryogenic treatment for enhanced edge retention and corrosion resistance.

What Makes This Different

The cryogenic treatment process subjects the D2 steel blade to sub-zero temperatures, refining the grain structure for superior hardness and wear resistance compared to standard heat treatment. The micro-textured anodized aluminum handle provides secure grip control while maintaining a lightweight profile. SOG's dual-action safety mechanism prevents accidental deployment while ensuring reliable activation under stress.

Key Features

• 3.43-inch D2 tool steel blade with black TiNi cryogenic treatment
• Automatic spring-assisted opening with dual safety locks
• Tactical tanto point geometry for piercing and utility tasks
• Micro-textured anodized aluminum handle scales
• Reversible pocket clip for tip-up or tip-down carry
• Plain edge configuration for clean cutting performance
• Compact folding design suitable for EDC applications

Field performance centers on the D2 steel's ability to maintain a sharp edge through extended use while the automatic mechanism provides one-handed operation in tactical situations. The tanto blade profile excels at penetration tasks and detailed cutting work. Weather resistance comes from the TiNi coating and sealed pivot construction that prevents moisture infiltration during outdoor use.
