The Megabite blade uses a high carbon SK5 steel in a tapered blade design, combined with an impulse-hardened 4 edge tooth that has improved tooth geometry for unmatched cutting performance and a longer cutting life. Each section of the telescopic extension arm locks down individually, creating an incredibly sturdy saw that can extend up to 5 feet.
