To simplify the setup of a bar and associated tools of a knitting machine and to improve the degree of precision regarding fineness and the level of sturdiness of the tools and bar system, the holding parts (7, 9) of the tools (4, 5) of the tool set (2) are configured differently. On the holding parts (7) of at least one tool type, means (22) are provided for positioning the tools (4) on the bar and thus means for defining the division. Separate positioning means for positioning and defining the division may be assigned to the other tools (5). Alternatively, they may be positioned by the tools (4) of the first type, between which they are accommodated. If positioning grooves are provided in the bar or parts thereof, these grooves may be set up for twice the distance of division, which results in robust and mechanically stable solutions with finer divisions.
