Abstract: The manual tool comprises: a handle (2) provided for manual gripping of the manual tool; an end (4) including an application head (4.1) formed by a sieve having an overall symmetry of revolution around an axis of revolution (X), where the sieve delimits a hollow volume interior in which a coating product runs out and has a set of openings, and each opening is formed for the flow of the coating product; a rotary support (6) attached to the handle to freely turn around the axis of revolution; and a removable fixing unit to fix the end to the rotary support in a removable manner. The manual tool comprises: a handle (2) provided for manual gripping of the manual tool; an end (4) including an application head (4.1) formed by a sieve having an overall symmetry of revolution around an axis of revolution (X), where the sieve delimits a hollow volume interior in which a coating product runs out and has a set of openings, and each opening is formed for the flow of the coating product; a rotary support (6) attached to the handle to freely turn around the axis of revolution; and a removable fixing unit to fix the end to the rotary support in a removable manner. The openings are distributed on the surface of the application head. The head application has: a shape of a cylinder coaxial to the axis of revolution; a conical or truncated form that is coaxial with the axis of revolution; and a length measured parallel to the axis of revolution to be 15-25 mm. The rotary support is attached to the handle by two needle bearings. The removable fixing unit includes an O ring configured for the handle reversible at the end on the rotary support. The handle has an oblong form extending along the axis of revolution when the end is fixed on the handle. The end comprises a base plate to which the application head is attached. The base plate is formed to cooperate with the removable fixing unit, and includes a supply pipe emerging in the hollow interior volume and crossing the base plate. The tool further comprises a product coating dispensing device that includes a manual actuator arranged for selectively allowing or preventing a flow of the coating product between a volume of storage and the supply pipe, and a connection unit to connect a coating product controller pertaining to the manual tool to a drain connected to the volume of storage. The manual actuator is formed by a lever movable between a closing position, in which the lever closes the controller, and an opening position, in which the lever opens the controller. The manual actuator is formed by a piston. The volume of storage is formed by a storage chamber placed in fluid communication with the supply pipe. The piston is mobile in the storage chamber so that the coating product runs out in the storage chamber when the piston is moved in an aspiration direction, and the coating product runs out towards the supply pipe when the piston is moved in a repression direction opposite to the aspiration direction. Independent claims are included for: (1) an application assembly to manually apply a coating product to a textile material slice; and (2) a method for manually applying a coating product to a slice of textile material.
