The Andis Envy Adjustable Blade Clipper (model US-1) is a corded professional hair clipper built around a magnetic motor that runs at 7,200 cutting strokes per minute, with a carbon-steel blade that adjusts from size 000 to 1 using a single thumb lever and can be closed to zero-gap for outlining and fades. It cuts wet or dry hair and weighs about 19.4 oz.
The clipper runs on 120V/60Hz household current and includes an internal power-adjustment screw so the motor output can be fine-tuned if the blade starts to clatter. A single switch button controls the tool — slide it forward to start, back to stop — with no multi-speed or heat settings, since it's a cutting tool rather than a thermal styling tool. Attachment combs snap onto the blade teeth for longer, guarded cutting lengths.
As with any adjustable-blade clipper, the blades should be oiled before, during, and after use and checked periodically for heat build-up during extended cutting sessions. Andis positions this clipper for barbershop and salon use.
