http://www.youtube.com/watch?v=_3-j2WuVDBI I came across it while looking for their rotary landscape blade trimmer; it appears Maruyama, Kawasaki, and Redmax are the only ones with a blade trimmer, and the RedMax is not a multi-tool. The backpack is 30cc but clearly uses a cable rather than a shaft from the motor to the connection. Does it work? Does it make sense? Does anyone have it? Are there any competitive products?
