Flowbee
If you were a kid in the 1980’s, then you might remember Flowbees, one of those weird inventions that made an impact. Basically, it was something like a vacuum that sucks up your hair and then cuts it. It was a pair of crisscrossing blades that trimmed the hair pulled up by the vacuum. The Flowbee cuts hair at one-quarter inch, so you didn’t have to worry about losing an entire head of hair in a matter of seconds, which is what would concern us (Seattle Times).
