3:24 The knife sheath has a strap with a press stud on the handle. This secures the knife. The knife would therefore not fall out of the sheath. 1:18 The handle is also serrated only on one side. Without gloves, I therefore always know where the knife edge is located. My hand gives me the feedback. The knife does not really need a concave grind (imho). I have given the cutting edge a smaller angle. The 1.2235 steel is ok for this. Now it works perfectly as an outdoor knife. Only years of use will show whether a plastic handle is good. Hopefully the plastic handle of the Armiger 4 will withstand all the strain for years to come Thank you very much for your good Video.
