Abstract
This tool substantially extends in a general plane (XY) and comprises: —at least one working head (12, 13) intended to cooperate with the fastener; —a handle (14) which is integral with the or each working head; the handle extending along a longitudinal axis (X-X) and comprising a linear portion (15) and at least one connection portion (16, 17) which connects the or each working head to the linear portion, the linear portion of the handle having a section transverse to the longitudinal axis (X-X) which comprises a relatively large transverse dimension substantially parallel with the general plane of the tool (XY) perpendicular to the longitudinal axis (X-X), and a relatively small dimension perpendicular to the general plane of the tool (XY). The large dimension and the small dimension of the transverse section are changing along the longitudinal axis. Use in flat wrenches, combination wrenches and ring wrenches.
