Rolling Knife Sharpener Kit, 4 Magnetic Angle Base 12/15/20/22°, Roller Knife Sharpening System for Pocket Knife, Kitchen Knives, Chef Knife Set (SET-A)

I was looking at the work sharp rolling sharpener and was almost there. And then I found this one.What made me buy it? Cost wise this unit is less expensive and comes with several more stones. The angle block has a 12* bevel and that is perfect for my chefs knife. So whats wrong with it? You have to unscrew the dick if you want to change grit. I use 400 and 600 for quick edge that is paper sharp. Every few months I will go through my bag and tune all of my knives. I go in steps 400 and up. I will never use a pull through and using a whetstone knife sharpener is a pain.

If your careful, it works very well. The negative I found was the magnetic holder has a rubber tape covering the magnets that gives the blade movement. Therfore if you don't give the same pressure each stroke, it bends the blade causing different grind angles. Everything else seems to be acceptable, especially for the price. Water the stones.
