On that safari, I had seen what looked like a "knobkerrie" (sp ?) club with s piece of leaf spring from an old car, fashioned into an axe blade. It was being used around the camp for cutting firewood and such. I asked the PH about it and if he thought I could buy it from the staff. He said, "Oh, you can't buy it from them. I got it when I was up in the North end of the country. So it belongs to me, and I just gave it to you."
So it is not just a souvenir, it is a treasured gift. But if I hadn't gotten one that way I would still have bought one on that trip or another one later on. It is a great conversation starter when we have guests.
