UBB.threads Forums Edged Weapons HJ Edged Weapons Forum Two HJ knives, doubts of authenticity

Dear forum users.
I just started collecting knives of the 3rd Reich. I bought two Hitlerjugend knives with authenticity guarantee from a private seller. The knife without motto is very similar to the original, but the second one has doubts about the grip plates, namely non-magnetic grip rivets and small backlash on the grip plates.
Thank you very much for your time and knowledge.

Best regards
Dan
