Some folks will think what they want, and there is as much bad info on the net as there is fact. Your knife isn't old at all, like likely less than thirty years old, and it was not a factory made knife it is a put-together knife. I'd suggest you take it to a knife show and talk to those who really know. I have been collecting knives for over fifty years and have many many books and thousands of knives. I am a life member of the Northeast Cutlery Collector's Association and a member of the Empire Knife Club and attend ten or so knife shows a year. One of my areas of interest is American fighting knives, and believe me, your little bladed knife would not cut it as a fighter. A fighter needs to be long enough to pierce deep into a large torso and yours will not do so. Remember a push dagger although it has a short blade has a long tang giving it the ability to pierce deeply.
