Some handles such as the 6 pin are two seperate slabs which enclose the full tang. I have two originals that only have 5 pins, but they are identical to the 6 pin style.
Some blades only had a very short tang which was inserted into a sawn slot handle and secured with 3 pins. My Father had one of these that he used as a utility knife. The blade had been broken at some time.
Another type had a short pointed tang made for pushing into a handle, the same as a metal file. I also managed to purchase two of these in a second hand shop.
This lower one I use as a hunting knife. When I made a handle for it I drilled through handle and tang and inserted one brass pin to help secure the blade.
