Sharp knifes are essential in your kitchen. I was inspired by another 3D printed knife sharpener (http://www.dr-henschke.de/Messerschleifer.html) and adapted the design for relatively cheep Chinese water stones as you can find them on Aliexpress. Additionally I simplified the geometry to reduce the number of parts and to make the assembly easier.
