ive not dropped a single guitar before.
strap locks all the way for me. i put them on stands which are out of the way of traffic when im taking a break from playing and store them in hardcases when not in use. i give myself a wide berth when playing my guitar , make sure my belt buckle aint sticking out, t shirt covering any rivets on jeans, dont wear shirt with buttons and use a static duster to brush of any traces of dust and dirt on my guitar before polishing. string my guitar really carefully so the strings dont scratch the finish and use non abrasive cloth and polish. i also clip my nails really short so theres no chance of making any indentations on the fingerboard.
just some of the things i do to take care of my guitar.
