Learn More About SOG One-Zero Knives

The SOG One-Zero series bridges the gap between a refined daily carry and a rugged tactical tool through its premium finishes and robust XR Lock. These knives utilize high-performance S35VN steel and chamfered ergonomics to deliver a professional-grade cutting experience.

What lock does the SOG One-Zero series use?
The One-Zero uses the SOG XR Lock, a crossbar-style mechanism that allows for smooth, ambidextrous opening and closing. This lock is known for its strength and provides an exceptionally tight lockup with very little blade wiggle during use.
What materials are used for the One-Zero blade and handle?
The One-Zero series features blades made from CPM-S35VN stainless steel paired with aluminum handles. This combination ensures long-lasting edge retention and a lightweight, durable frame that offers a secure grip without being overly abrasive.
Does the SOG One-Zero come in different versions?
Yes, the series includes both manual and automatic deployment options, as well as multiple colorways like black, white, and smoke gray. Some variants also feature specialized blade finishes, including two-tone satin or black Titanium Nitride coatings.
How does the SOG One-Zero carry in a pocket?
The One-Zero is designed for discreet carry with a reversible deep-carry pocket clip mounted at the very end of the handle spine. This configuration allows the knife to sit low and unnoticed while remaining fully accessible to both right and left-handed users.
Is the SOG One-Zero suitable for hard work?
While the One-Zero has a refined appearance with polished accents, it is built on a hard-working pattern capable of demanding daily tasks. The tapering drop point blade and secure XR Lock make it a versatile tool for those who need a knife that looks sophisticated but performs reliably under pressure.
