Why the old duffer does this on a $15 knife I've no idea."
Probably because he grew up in the days when you looked after everything you owned, repaired it when it broke and rarely threw anything away because you knew how to fix things and there was always somewhere to go to buy spare parts if you couldn't fix or make your own spares.
In other words, the olden days, before we became a throw-away society.
