this knife is post WWII but I hope you will find it interesting. I aquired this Iban tracker-scout from an SAS veteran from the early years of the Malayan conflict in the 1950s. The sword has one side convex and the other concave, most probibly made from a car spring. The blade is 20 and a 1/2 inches long and 1 and 3/4 inch wide at its tip. Apparently the trackers were quite happy to swop these knives for cigarettes but would never include the skinning knife attached to the rear of the scabbard. You can just see in the second picture the recesses in the scabbard where the binding for the skinning knife went, also on every scabbard was carved a small face, pic two, this was I am told all tied up with head hunting, which these scouts still indulged in. The hair decoration is human. John.
