Have you seen the ad for the “Handheld battery powered chainsaw” made by Stihl? They have videos of this really cool looking portable Stihl chain saw trimming trees and shrubs. Comes complete with battery, charger and handheld chainsaw, all for the low price of $29.99 plus $7.99 shipping.
What you receive is a chain with two handles attached at each end.
