I recently purchased a 1/6 K water stone. I sharpened my blades with the 1 K,4 K,6 K and 10K. The one I'm using now I breadknifed due to chips in the edge before honing. When I used it, I cut (hairline) myself without taking a stroke. I don't seem to understand why though. Have I over honed my blade? How do I correct this?
