This innovative and knife sharpener with its two separate sharpening modules sharpens knives simply, safely and effectively. It is easy to use because, in contrast to the sharpening steel, the angle is pre-set. Thus it is nearly impossible to use this sharpener the wrong way. Using its steel wheels, module 1 is able to gently remove small damages to the edge. Module 2 gently smoothes the edge and restores the knife to its high sharpness. Beyond that TWINSHARP Select works equally for left- and right-handers.
