I came across an old khukri that I purchased many years ago. It is 18 in overall in lenght with a wooden handle and brass fittings stamped 1917 and the shape of a ww11 fighting blade. It is in perfect condition as well as the sheath. Can anyone tell me how much such a knife is worth? And, is there anyone out there that can resharpen and polish the blade? Thanks in advance for your help.
