The Extrema Ratio Dobermann IV Classic is a fixed knife, based on one of the most classic Extrema Ratio knives: the K1 DOBERMANN. This knife is a true all-rounder - hunting, tactical use, survival: the Dobermann feels at home everywhere.
The blade is made from Böhler N690 steel, which is very corrosion-resistant and can really take a beating. It also has good sharpness retention. The blade is fairly thick. However, it has a neat, thin grind and a razor-sharp edge. The spine also has a swedge, which is a false edge that thins the blade to save weight. Because of this combination, a thicker part runs through the middle of the blade, giving the long blade its strength at the tip. A smart design, built to be used for years.
The handle is made from durable Forprene plastic. It's sleek and it feels comfortable in hand.
The sheath of the Extrema Ratio Dobermann IV is also very luxurious. The leather shaft is lined with a kydex insert. A diamond sharpening stone is also included in its own compartment on the sheath. There are various attachment options allowing you to attach this sheath in many ways. You can have the Dobermann horizontally or vertically on your belt, but also on a MOLLE system.
The Extrema Ratio Dobermann IV is a large, appealing hunting knife for the hunter, soldier or collector who only wants the best. It doesn't look out of place in a display case, but at the end of the day, it has been made to be used.
