We have had these threads before.. Just don't do it. Lesson learned for the final time. Just got my favorite screwdriver back from my roommate, totally stripped and gnashed up. It was 11 years old, my grandfather, who died of MS a couple years ago had bought it for me. Had the interchangeable bits in it. Some of those screw drivers were cheaply made, not this one. held up better than the others ive had. it had a square handle which i really liked too.. I dont see many with that feature. Just a screw driver.. but come on..
