Bill D., My wife bought me a 3 stage Chef's Choice motorized sharpener several years ago. After working a year in a hog processing plant when younger, most people never know what a TRULY sharp edge feels like....It is dull unless it cuts through 34 degree meet like a hot knife cuts butter. Imagine making 8000 cuts a day if you had to saw or pull/push hard!

Here is the style sharpener I have...it works on all style blade cuts, even serrated. Caution, it gets sharper than a razor!
