This saw is designed to work like other folding saws, only better. Made of premium high-carbon steel, Hooyman’s MegaBite™ blade features a special four-edge tooth design that cuts better than any folding saw you’ve ever used. Attach it to the extension handle, and it turns into an extendable saw. Each section of the telescopic extension arm locks down individually, creating an incredibly sturdy extended saw. The arms are constructed of aircraft-grade aluminum in a super-strong I-beam configuration. It’s lightweight, sturdy, strong and eliminates the downward flex you get with traditional pole saws. A replacement blade is also available. Available: 5 ft., 10 ft., Replacement Blade.
