Fanno saw blades have been popular with tree care professionals for decades. This Fanno saw blade comes with a Japanese tri-edge tooth pattern, which will make quick work of branches and limbs. This blade also comes with a gullet tooth design, which cuts very rapidly in soft woods, due to the improved chip clearance. Fanno Tri-edge blades are easily installed on most pole pruner heads or Fanno handsaws with the aid of a screwdriver.
