The **Extrema Ratio Dobermann IV Africa** is a fixed knife, designed and made for professional hunters. This is one of the most luxurious hunting knives in our range. 



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 standard handle is made from rosewood, a high-end material that makes this hunting knife a touch more elegant. Would you prefer a low-maintenance version that can withstand changes in temperature a little better? Extrema Ratio has the solution: a handle made of forprene plastic is also supplied. You can swap the handles with the included Allen keys. The wooden handle has a leather wrist cord, and the forprene version has a piece of paracord.



The sheath of the Extrema Ratio Dobermann IV is also very luxurious. The leather shaft is lined with a kydex insert. An awl and a diamond sharpening stone are also included in their 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 Africa is a large, appealing hunting knife for the hunter 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. Is the Dobermann IV a bit too big for your needs? Then take a look at a slightly smaller alternative: [kato://title/ER04.1000.0185-AFR](kato://product/ER04.1000.0185-AFR).

I wish I could have given 5 stars - I think this is a 5* knife - but the Africa package is a lot of money and it's not perfect. First of all I have to say that this was a slow burn, I love it now, it wasn't love at first sight!

I don't like the wooden handle, particularly the large shiny brass screw; the shape of the handle; the retaining strap that's positioned to become a certain and early casualty of the razor sharp blade; the writing on the blade; the leather thongs attached to all and every item; the price.

The Africa comes with two handles, the wood one with large shiny screw and a plastic/rubber hybrid with two smaller, un-shiny, screws. (Incidentally, the hybrid handle for the Africas is longer than the one on the Classic and the Black - it's the same handle as the Selvans). First thing I did, after sleeping on the decision to return it, was swap the wooden one for the quieter one. It now looks better, feels great in the hand and I can appreciate what a wonderful innovative shape the handle is. Hand to the back of the generous handle leaving one finger in the cutout for chopping, hand further forward and two for cutting - it's great, well designed. Next, I used the marlin spike (?), to help undo the knots in the leather thongs and took them all off - much better. Finally, I gave the sheath - which, like an expensive pair of unworn shoes, you can't begin to bond with until it's had a polish, a coat of neats foot oil and familiarised myself with the positioning of the retaining strap that will move out the way and doesn't have to suffer if you're careful.

This is undoubtedly a fabulous quality knife - particularly the deep, wide, uniquely shaped blade, which comes sharp as a cutthroat razor. I adore it now, and like all things you grow to love, you change the things you can (handle, thongs) and learn to live with, and grow to love, everything else (writing on the blade, marlin spike, funny shaped handle).

To me, more orthodox knives I lusted after seem less attractive since I got the Doberman IV Africa. A lot of money well spent!

The country of origin is the country the product is produced, as far as we know. This may differ from the country where the brand itself is located.

General information

We always measure the blade height at the highest part of the blade.

Blade height

We always measure the blade length ourselves. This is the length of the blade from the tip to the front of the handle. This may deviate from the manufacturer's specification.

Blade length

We always measure the blade thickness at the thickest part of the blade. Often just before the handle. This may deviate from the manufacturer's specification.

Blade thickness

value_handle_length

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.

Weight

Dimensions & weight

value_steel_hardness

The hardness in Rockwell C for a knife is always according to the manufacturer's specifications. When a manufacturer specifies a value of 56-58HRC, for instance, we always note the highest value, i.e. 58HRC.

knife_best_use

We like to highlight what use the manufacturer had in mind, or what we believe the knife is suited for

Best use

This concerns the type of edge [Want to learn more about a serrated versus a plain edge](/en/ct/pocket-knives-difference-plain-edge-serrated.htm)?

Type of edge

molle_compatible

MOLLE is a mounting system that allows you to attach sheaths and other accessories to backpacks. With this specification we indicate whether a product is already MOLLE-compatible by default. [Want to learn more MOLLE](/en/ct/what-is-molle.htm)?

MOLLE-compatible

We measure the sharpening angle ourselves. This value is the angle per side.  So 20º means that the total angle of the edge is 40º. Please note that knives are almost always sharpened by hand, even in factories. This value is therefore only an indication of a single tool measured by us. You are always free to choose your own sharpening angle. [Learn more about sharpening angles](/en/ct/sharpening-angles-explained.htm).

Sharpening angle

In terms of grind we are talking about how the complete blade thickness extends into the edge. Want to learn more about grinds? [Read all about grinds on knives](/en/ct/knife-grinds.htm).
