Abstract: A blade calibration gauge for a bladeset for a hair cutter has a moving blade laterally reciprocating relative to a stationary blade, where the moving blade and the stationary blade are adjustable relative to one another in a direction normal to a direction of reciprocation. The blade calibration gauge has a base defining a recess configured for receiving the stationary blade and providing a first stop for engaging a toothed edge of the stationary blade, and a second stop on the base disposed relative to first stop for providing a designed offset spacing for a toothed cutting edge of the moving blade relative to the corresponding toothed edge of the fixed blade.

Abstract: A hair trimmer or other attachment can be secured to a conventional hair clipper. The attachment has a stationary blade and a moving blade that cut hair when the moving blade reciprocates. The moving blade of the attachment is driven by a moving blade of the hair clipper, which also reciprocates. The attachment has a housing which secures the attachment to the stationary blade or other part of the hair clipper. A drive member engages the moving blade of the hair clipper when the attachment is secured to the hair clipper, and the drive member in turn drives the moving blade of the hair trimmer attachment to cut hair. The attachment can be easily detached so that the hair clipper blades can be used to cut hair in the usual manner.

Abstract: An air pulse attachment for a handheld dryer includes a shell defining a passage within the shell. The passage in the shell communicates the dryer with an outlet.

Abstract: A bladeset for a hair clipper includes blade teeth configured to guide hair strands toward a cutting zone and to retain hair strands in the cutting zone. By more effectively guiding and retaining the hair strands into the cutting zone, more complete hair cutting may be achieved. Another feature of the present self-cutting hair trimmer is a housing configured to provide a cutting line associated with a generally elongate handle, which in turn provides a bladeset angle of attack substantially perpendicular to hair to be cut on all parts of a self-user's head or a subject's head when the present trimmer is held by a user in either hand.
