Bests & Worsts Reviews from Amazon

I am a retired chef and have always sharpened my own knives with a sharpening stone which was a long and tedious process. This device is quick and sharpens my knives better than the old way. Be sure to exert downward pressure when using the unit and use more strokes than they recommend. I highly recommend wiping the knife clean after each step and be sure to clean the sharpened blade before using it.
