Came across this since i bought one of the global knife sets recently and will need a sharpener. This one seemed to get good reviews and it's the cheapest i could find.
Product description
This Minosharp Plus 3 ceramic water sharpener is extemely easy to use and recommended for sharpening GLOBAL knives and most other knife brands. This device employs three ceramic wheels - coarse, medium and fine to return a dull knife to working order. Fill the wheel compartment with water so your blade is continuously washed and cooled while it's being sharpened. Draw the knife back and fourth seven or eight times through each stage. The sharpener's plastic handle is shaped so it can be gripped firmly and safely and has a soft, rubber-like insert for comfort
Good if you dont want to learn how to sharpen a knife using a whetstone.
They usually make the wheels on these alot harder, and they usually shave off more material than you would do on a whetstone.
So be careful about going hard on these sharpeners you will decrease the life on your blade significantly.
I only use these types for cheap knifes, like a pyrolux or a mundial knife set. For any more expensive ones, i would use a whetstone.
