My Very Old Swiss Army Knife

Having moved from country to country, I have very few possession that I kept with me over the years. This Swiss Army Knife is one. My father bought this for me when I was very young. I do not remember when exactly but checking the stamping on the blade against this webpage, it is a pre-1973 ecoline model.

I remembered my dad taught me how to sharpen it on his wetstone, and I have sharpened it many times. There is a chip in the main blade but I do not remember when I chipped it. I have kept this in actual use with me as I moved from Hong Kong to England to America, as well as a lot of trips overseas. Recently I decided to "semi-retired" it to my desk drawer at home, so that I can pass this on to my kids.
