Good quality knives need to be looked after & must be sharpened from time to time. When subjected to wear & tear, through contact with the object being cut or with the chopping board.
Even the best knife will lose it’s edge eventually. It’s never any fun or safe to use a blunt knife do yourself a favour & buy the best.
Stone sharpening is an art, although like all things in life practice & persistence is the key!
