I have the electric TrueCut and love it. It works great! For those of you who don't like it, try putting a drop of oil on each stone before you sharpen, then again after each sharpening pass to clean off the metal residue from the stones. Rub the oil lightly with your finger and blot off the dark oil with a tissue, paper towel or scrap piece of cotton. Reapply another drop of clean oil to each stone for the next sharpening pass. It's time consuming, but the correct method. A metal clogged stone won't sharpen. Ask anyone who sharpens knives or surgical instruments.
