Horl 3 review- highly recommended!
"This device is a legitimate sharpener- it is not a gimmick. The concept is rather brilliant, actually. Everything about the product is made to feel like a premium product. But does it work? Absolutely! I picked up the premium discs as well as the Coarse disc (valuable for dull or neglected blades)- and I had all of my knives razor sharp in no time. The magnets in the block are incredibly strong. I have had no problems sharpening large chef knives and small paring knives. The included diamond disc is perfect for knives that are in decent shape. But consider the coarse disc if you have chips or if you want to reprofile a blade in short order. Using the higher grit discs and leather strop are great for taking the blade to the next level of sharpness. Make sure to do your homework on which angle to profile your blade to. One AI system told me the wrong angle that sent me off on a wild goose chase. That isn’t Horl’s fault- just a friendly reminder to do your homework first."
