The KM2000 (KM designates Kampfmesser, literally "combat knife") is the standard knife of the German Bundeswehr, mostly used by the German Army. The knife is manufactured in Germany by the Eickhorn-Solingen company (aka "Original Eickhorn").
The knife is produced according to NATO regulations by the German company Eickhorn-Solingen Ltd. The assembly consists of three components: the laser cut 172 mm Black Kalgard coated, forged X55CrMo14 or 1.4110 (440A) stainless steel Westernized tanto blade, the ergonomic ambidextrous polyamide handle and screw. The entire knife weighs approximately 320 grams. The sheath for the KM2000 is turnable, and includes an adapter to allow it to be mounted onto the MOLLE/PALS load bearing system(s).
The KM2000 owes a lot of its fame to the fact that it is among the rare (if not the only) "tantō"-style military knife actually issued in significant numbers.
Based on the popularity of the design, the company has developed the line-up introducing many variations in shape, material used, colours. Later revisions of the KM2000 (as of 2008) use a different stainless blade steel alloy with better edge-holding properties, X105CrMo17 or 1.4125 (440C) Böhler N695 (HRC 57). Additionally, the company has introduced several new variants, like the KM1000 without a blade-coating, and the KM3000 with a spear-point blade instead of the KM2000's westernized-tanto point. The latter two are also being produced with sand-colored grips and scabbards intended in desert environments like Afghanistan. It is interesting to note that most of these variations are not actually issued in the German Army.
