For the sharpest tools, keep stones wet and flatten them often
William Tandy Young says waterstones cut more quickly and efficiently than oilstones, and the finish they leave on a tool’s edge is more consistent. He uses synthetic waterstones, and explains why he prefers them. He talks about getting the stones ready, how to store them, and the benefits of establishing a dedicated sharpening station in your shop. He also explains how to flatten stones and how to sharpen your tools with them.
