As a plumber I get into all kinds of situations. Today I was working on a job with marble walls when I came upon some stripped screws I needed to remove through a small hole. I put a KnifeEdge Bit into my hand held screwdriver because space was too tight and I was afraid of chipping the marble with a power tool. Your bit worked better than I ever thought possible. It just really worked and saved me a lot of time and trouble.It also saved the customer $130 an hour on what could have been a much longer job.
