A do-it-yourselfer who never discards the little screwdriver-tips that come in boxes of torx deck-screws, even though there's always a fresh bit included in every box of screws.
My buddies jokingly call me a compulsive torx-bit saver because I don't throw out still-usable screwdriver-tips from boxes of screws, but I figger that, hey --- I already paid for the tips when I bought the screws, so why not save them in case I need one to use with other screws in the future?
