From everyday carry knives to tactical knives, SOG offers a wide variety of products to meet the needs of hunters, outdoor enthusiasts, military and law enforcement personnel, and anyone who values top-notch gear. At Knife Depot, we are proud to offer a range of SOG knives, and in this blog post, we will delve deeper into the brand, it’s history, and some of the knives we have available.

The History of SOG

SOG Specialty Knives, Inc. was founded in 1986 by Spencer Frazer in Santa Monica, California. The brand is named after the Studies and Observation Group, a covert special operations unit that served in Vietnam. Frazer drew inspiration from the group’s unique blend of innovation, precision, and resilience to create SOG knives and tools that reflect these characteristics.

Initially, SOG produced a single model of knife called the SOG Bowie, which was based on the Bowie knife used by special forces soldiers in Vietnam. The SOG Bowie was a success and was soon followed by other models like the Tomcat, which was designed to be a large, tough, and reliable folding knife.

Over the years, SOG has continued to innovate and expand its product line, always keeping its focus on creating top-quality knives and tools. In 1996, SOG introduced its first multi-tool, the Paratool, which was designed for military and law enforcement personnel who needed a rugged and versatile tool in the field. Since then, SOG has continued to produce a wide range of multi-tools, along with folding knives, fixed-blade knives, and specialty knives designed for hunting, fishing, and survival situations.

SOG Knife Technology and Features

SOG knives are known for their high-quality construction and innovative features. Here are some of the technologies and features that make SOG knives stand out:

SOG Assisted Technology (S.A.T.): This technology is used in many SOG folding knives and allows the blade to be opened quickly and easily with one hand. The S.A.T. system uses a spring mechanism that helps to initiate the blade opening, making it easier and faster to deploy the blade.

Compound Leverage technology: This technology is used in SOG multi-tools and provides two levels of leverage to increase the cutting and gripping power of the tool. Compound Leverage technology uses a pivoting joint that doubles the force applied to the pliers, wire cutters, and other tools on the multi-tool.

DigiGrip: This is a unique pattern that is found on the handle of some SOG knives. DigiGrip is a series of small diamond-shaped cutouts that provide a secure and comfortable grip, even in wet or slippery conditions.

Blade Shapes and Materials

SOG knives come in a variety of blade shapes and materials, each designed to meet different needs and preferences. Here are some of the most common blade shapes and materials used in SOG knives:

Blade Shapes:

  • Drop Point: This is a versatile blade shape that is well-suited to a variety of tasks. The blade has a curved edge that makes it good for slicing, and a point that is strong enough for piercing.
  • Tanto: This blade shape is inspired by traditional Japanese swords and has a straight edge with a pointed tip. The Tanto blade is good for piercing and slicing and is often used in tactical knives.
  • Clip Point: This blade shape has a concave curve near the tip that creates a sharp point, making it well-suited for piercing and detail work.
  • Bowie: The Bowie blade is inspired by the classic Bowie knife and is known for its strength and durability. It has a clip point and a long, curved edge that makes it good for heavy-duty tasks like chopping and cutting.

Blade Materials:

  • AUS-8: A Japanese-made steel that is known for its toughness and corrosion resistance. It is often used in SOG’s entry-level knives and offers a good balance between performance and affordability.
  • VG-10: A high-quality Japanese steel that is known for its sharpness and edge retention. It is often used in SOG’s mid-range knives and offers superior performance compared to AUS-8.
  • S30V: A premium steel that is known for its exceptional edge retention and corrosion resistance. It is often used in SOG’s high-end knives and is preferred by many enthusiasts and professionals.
