New in the package Sabatier 3 Stage Kitchen Knives Knife Sharpen Sharpener Tool. My wife already had one of these that we were also gifted. They work great!!!

It is a Three Stage Knife Sharpener. There is a Diamond Prep/Coarse Stage and then a Tungsten Steel Sharpen/Medium Stage and finally a Ceramic Polish/Fine Stage. Each of the grooves is a different stage.
