Do you have any family traditions that are passed down from generation to generations? It could be a family name, food that is cooked at all family gatherings...
In our family, it is a First Time Event Knife.
We have a glass knife that my grandparents cut their wedding cake with during the 1800's. It is very delicate. My parents, me, my sister, all our kids, grand kids and now great grandchildren have cut their wedding cake also. We have cut baptism cakes, graduation cakes, etc. The blade is quite worn so only the first slice is done. When the photographs are being taken, we insist one of the knife be taken to show that it was at that event. The knife was used at my son's wedding and then again at the first birthday of his son.
Illegitimi non carborundum!
I don't want my last words to be, "I wish I had spent more time doing housework"
