The GM88, or Geistmesser 88 (Ghost Knife 88), is the standard-issue combat knife of the Belkan Waldreich's Wehrmacht, based on the design of the KM2000. It has an extremely sharp westernized tanto blade, which is about the width of a sheet of paper. The blade is woven from multi-walled superhard phase carbon nanotubes, made from graphene molecules. Due to the composition, the blade has the dull metallic luster of graphite. The blade also does not need to be sharpened, due to the properties of the nanotube structure.
