I don't just sharpen knives, to build a log cabin I am sharpening 4 or 5 chisels and I need 'em sharp. I have ceramic sticks, I have whet stones, and I have the little flat plastic sticks with the diamond sharpener.

The best knife sharpener is the Edge Eater. You can buy one on Ebay for 14 bucks. Sharpens with a slightly coarse edge that cuts so effectively. You can sharpen a knife with the Edge Eater in about 45 seconds.
