Still unanswered questions, Mikee.

Watching this over quite some time, I believe that the smaller unadorned knives, like that above but without the emblem, were successors to the well known larger HJ knives. Cost reduction perhaps, or acknowledgment that the HJ were not going on the laughing camping trips anymore ?

I'm not aware of any official notices terminating the larger older knives or announcing the smaller ones

As to whether they were also issued to the DJ or could be purchased by DJ members , I'm open minded. They are not very fearsome knives as such things go.

BDM ? Unlikely IMO, but wouldn't that be a great photo to find ?
