S.O.G SOG-TAC Auto 3.43" Folding Knife - Black TiNi Cryo D2 Steel Blade, Black Anodized Aluminum Handle, Pocket Clip Included

The S.O.G SOG-TAC Auto is a purpose-built automatic folding knife engineered for shooters, hunters, and field-working outdoors people who need reliable cutting performance in a pocket-carry form factor. The 3.43-inch blade is ground from D2 steel with a TiNi Cryo finish—a proprietary treatment that enhances edge retention and corrosion resistance, letting you depend on this knife in wet conditions or demanding terrain without babying it. The blade is plain-edged (no serrations) and deploys via automatic mechanism, giving you one-handed deployment when you need it fast.

The handle is built from black anodized aluminum, a material choice that keeps weight down while delivering solid durability and a non-slip grip even when your hands are wet or gloved. The micro-textured surface won't slip in your palm during work, and the anodizing is tough enough to handle camp life, truck duty, or a range bag's rough-and-tumble environment. S.O.G includes a pocket clip, so you can carry this knife deep-carry or tip-up clipped inside or outside the waistband depending on your rig and access preference.

Whether you're processing game, setting up camp, opening boxes at the range, or keeping a backup blade in your everyday carry stack, the SOG-TAC Auto delivers the straightforward cutting tool serious outdoors people reach for. It's not a showpiece—it's a working knife built by a brand with decades of tactical and outdoor credibility.

Frequently Asked Questions

What's included with the SOG-TAC Auto?

The knife ships with a pocket clip, giving you carry flexibility right out of the box.

Is this a one-handed knife?

Yes. The automatic mechanism allows you to deploy the blade with one hand, which is useful in the field, at the range, or when you're holding gear or game in the other hand.

What's the D2 steel and TiNi Cryo treatment?

D2 is a high-carbon tool steel known for holding an edge well and resisting wear. The TiNi Cryo treatment is an S.O.G proprietary finishing process that boosts edge retention and corrosion resistance, making the blade more durable in wet or harsh conditions.

Is the blade plain or serrated?

The blade is plain-edged, providing clean cuts without the snagging that serrations can sometimes cause in certain cutting tasks.
