Review on 🔪 CWOVRS Professional Knife Sharpener Kit with 360° Flip Design, Rotation Fixed-Angle, 4 Whetstone+3 Base Equiped Diamond Stones - Ultimate Kitchen Chef Knife Sharpening System by Jaime White

Edit, the seller resolved the issues almost immediately. They are very easy to work with and I can only recommend them. Initially 3 stars, upgraded to 4 stars with help from seller. Pros - Ease of use, good quality for the price of the tool itself, although some screws that should be knurled are socket head and some are knurled. Bolts must have a hex head for further tightening. It holds blades very well unless the blade has at least a 1/2 inch flat face. I wouldn't use it for daggers. Cons - 1000# diamond stone fell apart after 20 minutes of use, see picture. I think you can glue it back, but for $100 it shouldn't be. Wet bricks fall apart with every hit. Also, diamond stones didn't fit right out of the box, you need to adjust the knob first, which isn't stated in the instructions. You will need a digital protractor, which is easy with smartphones as shown in the pictures, but TEST YOUR PHONE FIRST with a real protractor. My phone was off 2 degrees even after calibration.
