S.O.G One-Zero XR Folding Knife, 3.10" Black Chrome Cryo CPM S35VN Blade, White Sculpted Aluminum Handle

The S.O.G One-Zero XR folding knife is a compact cutting tool built for hunters, backcountry users, and everyday carry who need reliable performance in a pocket-sized package. This folding knife features a 3.10-inch blade forged from CPM S35VN steel—a high-performance stainless alloy that holds a keen edge and resists corrosion in harsh field conditions. The blade receives a black chrome Cryo treatment, a cryogenic process that enhances edge retention and durability. It's the kind of steel and finish combo you'll find on purpose-built field knives that cost considerably more.

The handle is sculpted white aluminum, designed for secure purchase and comfort during extended cutting tasks. The aluminum construction keeps the knife light without sacrificing rigidity, and the sculpted ergonomics mean you're not fighting the tool when you're field dressing, processing firewood, or working camp tasks. As a folding design, it tucks into a pocket, pack, or kit without the bulk of a fixed blade.

S.O.G has spent decades building knives for military and tactical users, and that uncompromising design ethos carries through the One-Zero XR. This isn't a knife trying to do everything—it's a focused, well-executed folder that excels at what it's designed for: reliable cutting performance in the field or on the trail. Whether you're a hunter, outdoorsman, or someone who values a quality blade in their everyday gear, the One-Zero XR delivers S.O.G's engineering in a size that doesn't demand belt or pack space.

Frequently Asked Questions

What's CPM S35VN steel and why does it matter on a folding knife?

CPM S35VN is a premium stainless steel that combines corrosion resistance with excellent edge-holding ability. For field and hunting use, it means your blade stays sharp longer between touch-ups and won't rust in wet conditions—critical for backcountry work where you might not have immediate access to maintenance tools.

Is this knife good for hunting and field processing?

Yes. The 3.10-inch blade length and CPM S35VN steel are well-suited to field dressing and camp tasks. The folding design means you can carry it easily without the weight or bulk of a fixed-blade alternative, making it a practical choice for hunters and backcountry users.

What does the black chrome Cryo finish do?

The Cryo treatment is a cryogenic hardening process that improves the edge retention and overall durability of the blade. Combined with the black chrome finish, it enhances corrosion resistance and gives the blade a professional, low-glare appearance in the field.
