Knitting tool

A knitting tool (1) comprising:

• a shank (2), which extends essentially in a longitudinal direction (z) in which the knitting tool (1) is moved during knitting,
• wherein the shank (2) has, at every point along its length, a cross-sectional surface (8) which extends orthogonally with respect to the longitudinal direction (z) and along lateral (y) and elevational (x) directions,
• wherein each of the cross-sectional surfaces (8) has a centroid (9), through which an imaginary center-of-gravity line (4) runs that interconnects centroids (9) of all the cross-sectional surfaces (8) along the longitudinal direction (z),
• wherein the shank (2) has at least one functional portion (5) in which the imaginary center-of-gravity line (4) has a varying height, and in which a height dimension of the cross-sectional surface (8) in the elevational (x) direction is smaller at every point along a length of the at least one functional portion (5) than a height of the shank (6) within the at least one functional portion (5), wherein the height of the shank (6) within the at least one functional portion is a distance, in the elevational direction (x), between a lowest point of the shank (2) in the elevational direction (x) and a highest point of the shank (2) in the elevational direction (x) within the at least one functional portion (5), and
• wherein the at least one functional portion (5) has a length which is more than 20% of a length of the knitting tool (1),
• wherein the at least one functional portion (5) has subsections (7) in which an absolute value of a gradient of the imaginary center-of-gravity line (4) is between 0 and ∞.
