My dad made me a knife once. My great grandfather (dad's side) was a master carpenter and he used one of his old files for the blade. On the other side of my family, the great grands on my mom's side, the family homestead burned down decades ago and someone managed to salvage one of the spindles from the bannister on the main staircase and made a crappy candlestick holder out of it, so he used that piece of wood for the hilt of the knife. So, bunches of family history made into an artifact that I can pass down some day :)
