I had an East German entrenching tool too, the folding type with a wooden handle and a black head. Keyhole-shaped hole in the centre of the head for removing nails with, 'MADE IN DDR' (in English of all things!) stamped into it, saw edge down one side of the head, chopping edge down the other, no pick like the West German one, comes in a 'strichtarn' canvas cover. It's the best E tool I've ever gotten my hands on, solid as a rock, packed with tools and much better than the NATO tri-fold one in my opinion.
Anyone know where I can get my hands on another one? I took the head of my East German one and put it on the NATO tri-fold handle to get it to pack down smaller (best of both worlds with that head on it, but it does weigh a bit), and the remaining NATO head and East German handle have been united into one (that doesn't fold unfortunately, since the attachment block on the NATO head is too big to rotate it) that is now carried in the boot of the car, but I would love to get hold of a proper old East German one again just to use 'as is'.
