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在使用该刀具的初代型号时，其核心缺陷暴露无遗：不可拆分的结构使其在野外受污染后几乎无法完成清洁。这一缺陷在后续型号——M-1937/II（FKm II型）中得到解决，该型号于1941年起直至战争结束期间投产。除上述厂商外，包括E. A. 海比希（E. A. Heibig）在内的其他企业也参与了该刀具的生产。该二代型号的核心改进在于可快速拆解为各组件，以便进行清洁或更换受损刀片；且完成此类操作无需任何专用工具。  * [更多截图](http://www.artstation.com/artwork/q9gwVP) * [初代刀具（M-1937/I）](http://skfb.ly/opFtw) * [英式实验刀具](http://skfb.ly/opHt6) 数据来源：Objaverse 1.0 / Sketchfab
