Any cutting tool requires re-sharpening.
The main difference of a good knife, and now we are talking about Japanese kitchen knives, is the quality of steel, professional heat treatment and blade geometry.
Concept of geometry included: thickness spine of blade, shape of flats, and thickness of the cutting edge.
Each component can significantly affect quality of cutting potential & duration of sharpness retention.
Knife makers from Japan, made cutting edge on most products extremely thin.
This gives an excellent cut, but implies careful use, with exception to contact of edge with other objects that have high hardness.
With normal use, the sharpening service is required once every few months, since only a blade that is not used can exist without re-sharpening.
Culture of proper handling of high-quality kitchen tools in our country is just being formed.
There are prejudices and non-observance of elementary common sense, but such incident are infrequent and occur in all areas.
Our company is engaged in supporting the products offered. We restore knives, and repair blade damages.

With next sharpening, it should be increased a little more, s...
