DOBERMANN IV evolved from the first and most classic Extrema Ratio knife, the K1 DOBERMANN. Over the years, the DOBERMANN has undergone significant change in look and design to meet evolving consumer expectations and ever-changing trends, while at its core retaining consistency with the original 1997 design. This last iteration, too, excels at structural durability and flexibility of use: perhaps our most versatile knife, the DOBERMANN IV is suitable for hunting, outdoors survival, camping, defense, up to and encompassing military use. Available versions: DOBERMANN IV CLASSIC, DOBERMANN IV TACTICAL.
