I suggested using this to someone a while back. You can be creative, tweak things on the fly if you have to and have fun in the process. Totally in the DIY spirit.
dude, I would seriously consider the 220v Flowbee haircutting system if $$ is an issue. The Flowbee Precision Haircutting System is guaranteed to perform hundreds of precision haircuts, yet it can pay for itself in just a few months.
In the same fashion that hairdressers pull the hair up between their fingertips to give a layered scissors cut, the Flowbee uses the suction power of your household vacuum to draw the hair up to the desired length, and then gives it a perfect cut.....every time. Most popular hairstyles from 1/2" butch to 6" long pre-raphaelite tresses can be cut with Flowbee. The Flowbee spacers make it IMPOSSIBLE to cut the hair shorter than the length for which they are set. For that perfect tapered cut around the ears and neck, specially designed spacers are also supplied.
Here is a little history for your perusal. Every so often, an industry will experience a technological break through that revolutionizes the way it operates. Remember the industrial revolution? In order to achieve such a breakthrough, the new technology must out perform the old ie barbers and hairdressers. It must introduce new efficiency never before known, and it must save money. The Flowbee Precision Haircutting System is just such a breakthrough in the haircutting industry. The patented design of the Flowbee out performs traditional haircutting techniques by providing a perfect cut every time.
The Flowbee is ever so neat and efficient that you can give yourself a trim just minutes before a party, a date with a potential future partner, a rock and roll concert event or that important business meeting!
The beauty of the Flowbee Precision Haircutting System is that it keeps hair at just the right length...all the time. Now you can trim your hair as often as necessary to keep that perfect look. Never again will you look like an asshole with too long, matted and unmanageable hair. Never again will you have that dipshit "just - got - a - haircut" look! Now your hair can look the way you always want it to look...all the time! "
