Wahl
Illinois clipper manufacturer founded in 1919, a fixture of professional barbering.
Leo Wahl patented an electromagnetic hair clipper in 1919 and the company has been family-controlled ever since, remaining a default in barbershops worldwide.
Barbering is a demo category
Clippers sell from the chair. Trade stands are built around barbers cutting live, because feel, weight, balance and blade noise decide the purchase and none of them survive a spec sheet.
