The story of SOG^® Specialty Knives & Tools traces back to the Vietnam War, when members of the elite U.S. special operations unit MACV-SOG carried a distinctive combat knife during covert jungle missions. This original SOG Bowie knife later became an inspiration for modern innovation.

In 1986, designer Spencer Frazer founded SOG Specialty Knives with the goal of recreating the iconic SOG Bowie as a tribute to the special forces units that carried it. What began as a commemorative project gradually evolved into a globally recognized brand known for cutting-edge knives, multi-tools, and tactical equipment that combine advanced materials, functionality, and distinctive design.

SOG products are widely respected among military personnel, law enforcement officers, outdoor enthusiasts, and everyday users. The brand has built its reputation on reliability in demanding environments, blending tradition with modern engineering. Today, SOG tools are trusted worldwide in professional and recreational settings alike.

Technologies used by SOG

CPM S35VN Steel – An American-made steel offering excellent edge retention, high wear resistance, and improved toughness while remaining relatively easy to sharpen.

CPM S30V Steel – A premium powdered steel enhanced for corrosion resistance and durability. Known for its balanced performance, it is widely regarded as an excellent choice for versatile everyday knives.

Cryogenic Treatment – A specialized process in which blades are cooled to extremely low temperatures (around −185°C) and then returned to room temperature. This refines the steel structure at the microscopic level, improving toughness, wear resistance, and edge stability.

SOG Assisted Technology™ (S.A.T.) – A spring-assisted opening system that ensures smooth, rapid blade deployment once the opening threshold is engaged.

Arc-Lock™ – An ambidextrous locking mechanism designed for strength and safety. It allows fast one-handed operation and is engineered to withstand exceptionally high loads compared to many traditional lock types.

Compound Leverage™ – A proprietary multi-tool technology utilizing multiple pivot points to generate increased gripping force, making cutting and gripping tasks easier and more efficient.

Sharpening Rod in Handle – Selected models feature an integrated sharpening rod stored within the handle for convenient field maintenance.

Double Tooth Saw + Rotating Blade – A saw design with alternating tooth angles for effective cutting in both directions, reducing binding and improving performance.

Saw Back – Certain fixed-blade models incorporate a functional saw spine for deeper and more aggressive cutting.

San Mai Stainless Steel – A layered steel construction combining a hard core for edge retention with softer outer layers for improved durability and flexibility.

Automatic Mechanisms – Selected models feature automatic blade deployment systems activated by a button or lever.

VG-10 Steel – A premium Japanese steel known for high hardness, fine edge capability, and excellent durability, frequently used in high-end knives.
