Sharpening – How to Tell If a Steel Rod Is for Sharpening or Honing

I usually notice when cutting onions and tomatoes. With a very sharp knife cutting an onion doesn't cause much tears at all. As it dulls though it does more crushing than slicing which releases more gas into the air, which makes you cry more. Ripe tomatoes help because they are so tender. If it becomes difficult to slice a tomato without crushing it, your knife is too dull.

A well used, properly cared for knife should require sharpening every 6-18 months, depending on usage. Mine get sharpened yearly.

Stamped knives are stamped from a sheet of steel- therefore the metal is all one thickness (or thinness).

Forged knives will be thicker at the back and taper to the front.

So- a stamped knife will never have a bolster, a forged knife may or may not.
