An ergonomic dispenser of a roll of adhesive film facilitates application of that film to a surface with minimum manipulation by the user. The dispenser has a low profile where the cutting blade, axis of rotation of the adhesive film roll and dispenser handle lie in closely aligned planes. This creates a low profile dispenser which places the roll of adhesive film in close proximity to the application surface. A flexible shield overlies the cutting blade to prevent unwanted user contact with the blade. Various means are used to manage the loose end of film after it is cut off the roll so that it does not adhere to the roll or double over on itself. Unidirectional movement of the roll is also used to manage the loose end of tape after cutoff. Optionally, blade means may be added to the dispenser's handle for use in opening cartons, cutting string or the like.
