The Dobermann IV Silver from Extrema Ratio's K1 Dobermann series has become a beloved classic since its debut. This model has seen continuous enhancements, reaching its peak with the 2013 release of the Dobermann IV. Since 1997, Dobermann knives have evolved significantly to meet consumer preferences and market trends while preserving their original style. After the Dobermann III was discontinued in 2006, extensive design and development efforts led to the creation of this new model.

The Dobermann IV is crafted for versatility, featuring a robust yet agile internal structure. Whether for hunting, survival, camping, or military and defense applications, this knife is ready for any challenge. It is available in two versions: Tactical and Classic. The Classic version features a steel-colored blade and a heavy-duty leather sheath. Made from N690 steel, the blade delivers exceptional performance, with flat grinds on the spine and belly for superior penetration. Like the Dobermann dog, this knife is sleek, aggressive, and formidable.

The satin-finished steel blade is engraved with detailed specifications, and the lanyard holes at the base and tip can be connected with paracord for a secure grip during heavy use. The Forprene handle is secured with hex screws for easy cleaning and oiling, extending the knife's lifespan. Its high-grip polymer handle allows for quick grip changes, whether forward or reverse. The full-steel lanyard section at the handle's end is ideal for close-quarters combat.
