Woody Brand Knives are known for great edge retention and therefore should not require a lot of frequent sharpening. If and when they do, a ceramic or diamond rod or a leather strop will do the trick. If the knife requires re-honing after hard use, Woody suggests an Arkansas Oil Stone for re-profiling the edge. If you are not a skilled free hand sharpener then a system like ‘Lansky” sharpener is recommended. This will allow for keeping a precise angle on the bevel of the edge, key for getting a sharp edge.
