Review on Enhance Your Knife's Sharpness with KDS Combination Whetstone: The Perfect Sharpening Harder by Glen Needham

Very good stone for quality steel. I use it for my kitchen knives around the house. Unless you're a professional and don't sharpen your knives almost every day, this is all you need for your good knives and they will last you for a long time. I use it for knives with a hardness in the Rc 55-62 range. Burrs form quite quickly on hard steel. Unless your knives have been abused and don't need a full overhaul, the 1000 grit side will push your knives to the limit and create burrs fairly quickly. My standard of sharpness is pretty high, so I use 6000 grit most of the time. My knives are rarely so dull that they require 1000 grit sides. A disadvantage of this stone is that the instructions are not in English. The instructions are the blue card in the first photo and I believe they are in Japanese only. Minimal soaking for the 1000 grit side. The 6000 grit side is ready to use. After trying a few cheaper stones I'm glad I found and bought this one. A cheaper Kingstone 1000/6000 is available. Spend a few bucks more and get this one.
