Traditional style Itak or Golok is from Northern Philippines. With straight blade and square tip, it is work blade. Showing age the blade is 12” long, 2-1/2” wide at the tip and slightly thicker than 1/8” near the handle. A marking is located on the right hand side near the handle: JOC 88. The initials are probably the craftsman and 88 meaning 1988. The long handle is 7” long made from carabao horn or water buffalo and has 7 sides. A metal ferrule is used. The tang is pinned at the back of the handle.
Though the blade has some age showing and blade style is utilitarian, it represents some of the blades made 30 years ago.
