A hand held device ( 2 ) comprising a handle ( 4 ), an operational member ( 6 ), 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 guides the control member ( 10 ), 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 ), movement of the control member ( 10 ) along the guide groove ( 14 ) causes the folding of the operational member ( 6 ) via the arm ( 12 ), in its closed condition operational member ( 6 ) is folded into the handle ( 4 ) 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 farthest from both the first and second connecting formations ( 16, 18 ), and in its open condition the first connecting formation ( 16 ) is nearer than the second connecting formation ( 18 ) to the first end ( 20 ).
