The best construction is called full tang. The tang or handle part of the knife is full size and the handles are riveted to the tang with the tang showing all around the handle. Full tang knives are the strongest types. Bolsters are found on the best quality knives. They are the thick steel area between the sharpened edge and the handles.
Bolsters provide additional rigidity, weight, safety and improved balance to a knife.
All of the Sabatier and Henckels knives we offer feature bolstered construction. The best kitchen knives are flat ground. The blade profile tapers from the thicker spine to the thinner edge in a straight or convex line. They are heavier and tougher than hollow ground blades which have a concave profile. Serrations are the wavy type of blade edges.
