Chirra or fuller is a special and distinctive feature of a kukri knife. Its there for strength, stability, style and to make a statement. Fuller or Chirra is actually the grinding out the blade material in a symmetrical way shaping out like a channel. It not only reduces the unnecessary weight and provides a balance feel but also gives strength and stability by evenly distributing the shock felt by the blade on impact. It’s the hardest to craft and requires highly skilled makers to perfect it. SEMI CHIRRA khukuris are those that have half chirra/fuller in the panel of the blade. It starts from almost tip area and finishes around the peak area.
