Freehand sharpening with a whetstone will give you the best edge, but requires excellent technique. Great for kitchen, sporting, and hunting knives and tools.
Whetstone sharpening is by far the best method to sharpen your knives, but it takes time, practice, and skill to master. As with all abrasives, you’ll want to start with a lower-numbered (coarse) grit to remove steel and sharpen, and work your way up through the higher-numbered (finer) grits to fine-tune and clean up your edge. Many whetstones are “combination” whetstones, featured two grits that you can flip between.
