Wow, what a strange turn this thread has taken.
When I was a kid, living in the country, most men, and boys of around 8 to 10 years old carried pocket knives. One didn't use them every hour of every day, but there were reasons; whittling, cutting thread or other things like leather or cloth, cleaning or cutting fingernails, cutting food, playing mumblypeg (sp), and other non-aggressive or non-deadly things. I carried knives for years, usually inexpensive but serviceable. I was taught how to sharpen a knife, as that was considered proper, and a sharp knife was considered safer than a dull knife.
9/11 made it impossible to do so. I don't travel much any more, at least not by air. So I have learned to live without my 2 blade pen knife, and don't even consider my Swiss Knife or Leatherman. They sit at home waiting for the world to get better.
I don't recall I ever took a photo of any of my own knives. I wouldn't think it strange to do so though, as long as it was just a documentary thing of my property.
Fujilove - Sorry about your bad experiences. But if like me, your favorite 35mm camera is an ST 901, on a strap, it can be formidable for self defense.
In Seoul, Korea in the 80s, a large man approached another soldier on a dark and deserted street, and demanded the camera carried by the second man (an Olympus OM1). Realizing his predicament, the second soldier promptly gave it to him... holding it by the strap and swinging it into the head of the attacker. I was told it still worked after that too. 😀
