A one handed break that I made-up when I was in Junior High School. It could be the "official" way to do it, or it could be really poor form. I wanted to do a one handed cut, and there was no Internet to search back then, so I had to figure it out for myself.
Turns out it's a slight variation on one posted by FrenchCrawler
about a year ago, so I must not have been very far off the mark.
