The handle comprises an elongate shaft portion ( 3 ) with a handle end ( 3 a), a tool end ( 3 b), a longitudinal axis ( 5 ) and a pivot joint ( 4 ) comprising two joint members having a pivot axis ( 6 ) for rotating relative to each other and extending under an angle (alpha) relative to the longitudinal axis ( 5 ) and having swivel surfaces ( 10 ) which are in mutual engagement and slide against one another during rotation, in which the pivot joint ( 4 ) comprises a indentation mechanism comprising engagement means on one of the joint members, said engagement means being adapted to engage corresponding engagement means on the second joint member to determined a plurality of discrete mutual angle positions in respect of the two joint members. The engagement means comprises engagement faces, which are oblique, whereby the engagement may be released by subjecting the two joint members to oppositely directed torques exceeding a definite size and least one spring means is present for actuating the engagement means of the two joint members towards mutual engagement. The angle (alpha) between the longitudinal axis ( 5 ) and the pivot axis ( 6 ) is 20-70°. |
