This is a reproduction of the combat knife MK3 used by U.S armed forces ~UNBOXING~ D2 Tool Steel Sharpening Tips Demo@ End with Snowman So I've owned D2 tool steel knives before so I'm very familiar with its sharpening characteristics and general feel of D2 and all I can say is it behaves, sharpens like a D2 tool steel blade and this steel is hard as hell..... exactly like D2. D2 cutting edge will not go back and forth asymmetrical on a stainless steel honing rod! So I go back to my tried and true 30-40 degree sharpening angle with my 50/50 engine oil, it shows the carbon and the carbon is attracted to the engine oil, the oil is part of my success....not standard honing oil you've been wasting your money on all these years. Real engine oil and Slick 50 Engine treatment oil put this oil on a Arkansas stone or fine aluminum oxide stone for D2 tool steel or high carbon 1095 K-Bars. Generally I shy away from larger blade knives with D2 tool steel but on this smaller MK3 blade and it being thinner it appears to be an outstanding combination. What puzzles me is why these German manufacturer didn't label their MK3 here D2? It's got a shitload of carbon content and carbon cuts! D2 is super high carbon with around 12% chromium plus it has Vanadium! Vanadium teams up with the carbon which results in a longer lasting edge retention. Anytime you see Vanadium in a steel you're getting the body guard that protects the carbon. But with any knife you got to get your secondary cutting edge zeroed and symmetrical to achieve a razor sharp edge.
