I have a knife stamped CRAFTSMAN USA that I purchased from Sears around 1972. The knife is identical to the Schrade Deer slayer. Any idea what years this knife pattern was made for sears? The sheath is in very good condition and the knife blade has a slight patina. I plan to bring it to the camp next week and hopefully put it to use. I am not a knife collector, I just seam to keep things a long time, especially if they are well made.
