This is an authentic WWII German knife that was made for the Boy Scouts or other youth groups. It's a transitional piece that was made in 1938 by the WKC company.
It has the RZM markings on the back and it has the motto on the front. Handles were replaced at one point and the leather strap on the scabbard is very fragile. The knife doesn't have a lot of pits or corrosion.
Your package will come to you with more than adequate packaging as to keep it safe until it reaches you. I will try to keep the tape to a reasonable amount so you won't cut or stab yourself trying to open it. Also, it will be clean enough for you to touch it without having to wear gloves or grab the tongs. Please ask any questions you may have.If you need help with this please ask.
