A tendon is disclosed that comprises a plurality of indentations that have been cold-rolled into the tendon along the length and around the circumference thereof. Each 5 indentation has opposing edges which generally extend longitudinally and in parallel to a longitudinal centreline of the tendon. When the tendon is viewed in transverse cross section through the indentation from one edge to the other, and an axis is projected from the longitudinal centreline of the tendon to bisect a chord that extends between the edges, a base of each indentation can be defined by a radius which extends from a point 10 on the axis which is near to but offset from the tendon centreline. The radius can be approximately equal to or less than a radius of the tendon at an unindented portion thereof. The base of each indentation defined by the offset radius may extend for a substantial proportion of the indentation base when the tendon is viewed in transverse cross-section. A chord 'e' can be defined as the straight line distance between adjacent is edges of adjacent indentations. The sum of each such chord, when moving one revolution around the centreline of the tendon, can produce a value in the range of 0.1 of the circumference of the unindented tendon. r~-~ C-0 |
