Safety razor

A safety razor comprising, a handle element;

• a blade carrying head element provided with at least one blade;
• a rotatable element having an axis and connected with said head element so as to rotate relative to said head element but jointly move in an axial direction;
• means for imparting to said rotatable element a movement in the axial direction in response to contact of said rotatable element with a surface to be shaven, so that when a user moves said handle element and therefore the head element in a predetermined direction during shafing, said rotatable element and therefore said head element with said blade is displaced in a direction which is transverse to said predetermined direction in response to rotation of said rotatable element, said imparting means including a shaped groove provided in said rotatable element and a spherical member arranged between said handle element and said rotatable element and movably engaged in said groove of said rotatable element;
• and means for guiding said head element during its displacement relative to said handle element in said axial direction, said guiding means including an additional spherical member arranged between said handle element and said head element, said handle element and said head element forming first and second elements, one of said first and second elements having a substantially semi-cylindrical recess while the other of said first and second elements having a substantially spherical recess, said additional spherical member being received in said semi-cylindrical and said semi-spherical recesses of said first and second elements.
