DOBERMANN IV evolved from the first and most classic Extrema Ratio model, the K1 DOBERMANN. Over the years, the DOBERMANN has undergone significant changes in look and design to meet evolving user expectations and trends, while at its core retaining consistency with the original 1997 design. This latest iteration excels at structural durability and flexibility of use: as one of our most versatile tools, the DOBERMANN IV is suitable for field activities, outdoor exploration, camping, and technical or professional use..
