Abstract
A hair cutting device is connected to a vacuum source to draw hair into a cutting chamber and includes a mechanism for cutting which allows an operator to both position the cutting device and to activate the cutting mechanism with one hand. The cutting mechanism includes two blades and preferably at least one blade slidably moves against the other to cut hair. The cutting mechanism also maintains the blades in proper position and applies pressure to at least one of the blades to ensure the proper cutting of the hair. Preferably non-parallel cutting edges and the bowing of at least one of the blades act to provide an effective moving shear point between the blades. The cutting mechanism also allows for continued airflow through the cutting chamber regardless of the position of the blades during the cutting operation.
