Wonderfull pictures. Tipped me over the edge. I'll soon have Nepalese military kukri to compare to my H.I.'s. You folks are a really, really bad influence. So back to topic, are dui chirra style blades necessarily of an older design? It seems that the use of fullers would be to optimize stiffness and reduce weight for the, shall we say, more singular purpose built kukri. The dui chirra style has to be some of the most beautiful blades ever.
