A hand held device (2) comprising a handle (4), an operational member (6) which folds into and out of a side (8) of the handle (4), a control member (10) for controlling the folding of the operational member (6), an arm (12) which connects the control member (10) to the operational member (6), a guide groove (14) which is in the handle (4) and which guides the control member (10) over a path which causes the folding of the operational member (6), a first connecting formation (16) which connects the arm (12) to the operational member (6), and a second connecting formation (18) which connects the operational member (6) to the handle (4), the device (2) being such that movement of the control member (10) along the guide groove (14) causes the folding of the operational member (6) via the arm (12), the device (2) being such that in its closed condition the operational member (6) is folded into the handle (4) and the first connecting formation (16) is further away than the second connecting formation (18) from a first end (20) of the handle (4) that is remote from both the first and second connecting formations (16, 18), and the device (2) being such that in its open condition the operational member (6) is folded out of the handle (4) and the first connecting formation (16) is nearer than the second connecting formation (18) to the first nd (20) of the handle (4).
