I was looking at the Buck display case at work and I realized that there were two 118's on display, one of which was where a 105 was suppose to be. Upon closer inspection I realized that this knife was much older. The handle has four micarta spacers as opposed to two, and there is no date mark next to the model number. I asked my manager about the knife and he has no idea where it came from or why it was there. There is no box and no sheath so I convinced him to sell it to me for $10.00. I know it has to be older than 1986 because there is no date marking. Are there any other characteristics to look for that might tell me when it was made?
