Step 1 Examining Knife Sharpener

• Simple knife sharpeners only have on sharpening
  slot, but others have two or three. If the knife
  sharpener has multiple slots, the slots should be
  labeled according to coarseness. The coarsest
  slot will usually be labeled as "coarse" or "1,"
  and the finest slot will usually be labeled with
  the final number in the sequence or the word
  "fine."

Step 2 Insert Blade Into Coarsest Slot

• Position the blade in a straight cutting position
  in between the two sharpening disks.
• Keep the base of the blade as close to the disks
  as possible, and make sure that the blade remains
  perpendicular to the body of the device.

Step 3 Pull Blade Through The Slot

• Using light pressure, pull the blade back in a
  horizontal motion, drawing the blade through the
  disks from base to tip.
• Some knife sharpeners can be held by hand as you
  work with them, but it's usually easiest to use
  your non-dominant hand to hold the knife
  sharpener down on a table or similar work
  surface.

Step 4 Pass Through Same Slot Again

• Return the blade to its starting position, then
  lightly draw it through the disks again, working
  from base to tip.
• For each pass, start at the base and end at the
  tip. Do not pull the knife back and forth through
  the slot since doing so could damage the blade.

Step 5 Repeat Process With Remaining slots

• Work through the remaining slots, moving from
  coarsest to lightest. Draw the knife through each
  slot using the same technique as the first slot.
• Don't skip over any of the slot levels unless the
  instruction manual tells you to do so.

  knife, rinse away any shavings under cool,
  running water. Carefully dry the blade with a
  clean towel.

  ready to use again.
