This is a knife sharpener designed for common household use, and made more practical than singular knife sharpers that already exist on the market. A typical knife sharpener usually comes with only one angle and strength. However, K-sharpener’s hexagonal shape allows sharpening stones of varying angle and intensity to be inserted into each side of the sharpener. This accommodates different knife in various sizes and different sharpening needs. The strength of the sharpener changes in increasing order along the hexagon, with a difference of 1000 grids. The stones may also be switched in and out.
