As juliet notices very quickly, also the name of a very good brand of hair maintenance tools.
The Wahl Clipper Corporation became the world's leading manufacturer of electric hair clippers after Leo J. Wahl experimented with an electromagnetic motor in 1911.
On October 14, 1919, Wahl applied for patents and Wahl Manufacturing Company was born. This was the first practical clipper with the drive motor in the hand, rather than driven through a flexible shaft from a remote motor. Thus, the era of do-it-yourself haircuts was born and a thousand children wailed at once.
