The sharpener has interlocking chambers to collect shavings for mess free sharpening.  Sharp, long-lasting cutting blades sharpen pencils smoothly and precisely every time.  It tapers the pencil tip to the correct angle and point, and without breaking off the soft point of the pencil.  Easy to clean by just unlocking the chambers to empty out the shavings.

TIP: For the smoothest results in sharpening your pencils put them in the freezer first for about 15 minutes before sharpening them.
