Note

In general, knife steel is used for on-site sharpening in a handy way:

Pull-through sharpeners are simple and lightweight which are now widely used by most families.

Whetstones are a traditional sharpening tool, but which is inconvenient and require skills. Functionally speaking, the whetstone is the best tool for sharpening, in particular, a precision whetstone can give result to a sharp and durable knife. Because the whetstone gives out a fine and smooth blade in contrast of knife steel and pull-through sharpener, for the latter ones, the blade shows teeth under the magnifying glass, which is not really sharp and will not last long, or even will cause rough damage to the knife, so it is recommended to use the whetstone in a professional way.
