The presence
of air pockets in the design of the knife.
In its classical form, air pockets, or grantons, are small oval or oblong-shaped notches located along the blade. It is believed that they prevent the product from sticking to the blade, which is especially important when thinly sliced "sticky" foods like soft cheese. At the same time, the actual effectiveness of grantons can be different, it largely depends on the price category of the knife — the more expensive the product, the more carefully the manufacturer approaches the choice of the optimal shape of the recesses.
If we are talking about
cheese knives(see "Type"), then the air pockets are made in the form of continuous slots in the blade. At the same time, such slots can be quite large, so that the tool looks more like a “knife frame” than a full-fledged knife (although this impression is misleading).
