I'm not a doctor, so no. I haven't. In fact, I find the thought to be a bit gross. You can give yourself a horrible infection with a dirty knife, pin, needle, etc. I have pulled a splinter myself using a pin and was concerned with that. I'm a whimp when it comes to doing anything along those lines. Went to the doctor with a three-pronged fish hook hanging out of my foot too. Couldn't bring myself to remove it!
