I have a Imperial knife I bought when I was a kid in the 80s,I can't find any info on it.It was my favorite knife growing up. It is slightly smaller than a Buck 110,has Olive green plastic scales that used to have a Camouflage pattern on them that has since worn off,It is a lock back,and has a camouflage sheath.It has a clip point blade that is flat ground and has a swedge grind only on one side of the bladeThe Handle has finger grooves.The stampings on the blade are IMPERIAL under that is stainless.Under the brand and stainless markings are USA 5715. I bought it at Walmart over 20 years ago.thanks for any help.
