@colubrid isn't trying to restart an old thread as much as he's trying to find the edge of where "traditional" starts. His example is a knife that strongly resembles a modern knife. Sadly, he doesn't have this knife any longer so we keep coming back to that modern one. No, the Impinda isn't traditional. It's certainly in a gray area for some folks, though, colubrid included. Until we get a pic of that original knife, we're at a standstill.
As for innovative designs, colubrid, yes the Reichswehr certainly had them, though your exmple of the Luger P08 goes back to, well, at least 1908. Firearms are tricky, though. Would one call an M1 a "traditional" rifle? Well, maybe. What this leads me to consider is that "traditional" folders for this community refers to a body of knives that largely occupy a period of design from the mid 18h to the mid 20h centuries. Not that these are hard lines and not that the dates are exclusive. It just tends to shake out that way.
Again, as this thread hangs on a knife we can't see, it's about played out, so get us that pic!
