The 6.5" Double Bow Sheep Shear by Burgon & Ball are made from Sheffield steel. The shears have a rolled bow, which creates an easier action and increases overall strength. Heat treatment guarantees hardness and long-term edge retention of blades. Blades are double hollow ground (Hinds patent). Blades and shank are a single piece for increased durability and accuracy. Each shear is handset and tested.
