Kappmmesser М-1937/II (German gravity knife)

When operating the first model of the knife, its essential drawback was revealed - the non-separable design practically did not allow to clean the knife after contamination in the field. This flaw was removed in the next model - "M-1937 / II" (Type II FKm), which was produced from 1941 year to the end of the war. In addition to the above companies, knives were also manufactured at the enterprises of other companies, including the company "E. A. Heibig". The main difference of the second model is the ability to quickly disassemble the knife into its components for cleaning it or replacing the damaged blade with a new one. Moreover, to perform these operations, no special tools were required.  * [Additional screenshots](http://www.artstation.com/artwork/q9gwVP) * [First type of knife (M-1937/I)](http://skfb.ly/opFtw) * [English experimental knife](http://skfb.ly/opHt6) Source: Objaverse 1.0 / Sketchfab该刀具的初代型号在实际使用中暴露出根本性缺陷：其一体式不可拆卸设计，使得野外沾染污渍后几乎无法完成清洁作业。 这一缺陷在后续型号M-1937/II（Type II FKm）中得到修正，该型号自1941年起投产直至战争结束。除前述厂商外，包括E. A. 海比格（E. A. Heibig）在内的多家企业亦参与了该刀具的生产制造。 该二代型号的核心差异在于可快速拆解为各组件，以便进行清洁或更换受损刀片，且此类操作无需借助任何专用工具。  * [补充截图](http://www.artstation.com/artwork/q9gwVP) * [初代刀具型号（M-1937/I）](http://skfb.ly/opFtw) * [英国实验性刀具](http://skfb.ly/opHt6) 来源：Objaverse 1.0 / Sketchfab
