I hand sharpen my larger bits and custom bits. For many years I have had 2 drill doctors, one is set up to handle up to 3.4" and left hand bits. However my go to is my Grizzly H8203 that I acquired at the tent sale for $40 several years back. It was new, never used other than plugged in and it did not work (hence why i got it so cheap) The problem was a broken wire at the fuse holder. I do love a deal!
