White – I have been teaching myself to sharpen knives and tools for 2 yrs. This spring bought an old grinding wheel. Go to a thrift shop and buy all the knives u can…practice, practice. You will have many small cuts as u learn. Keep super glue or New Skin on hand! Learn to use the sharpeners you can buy, small, for serated knives as well. Chain saws are one of the hardest. Good luck n have fun…it is a useful skill. I have hairdressers that pay me to sharpen their scissors n I make some nice side money on that.
