Unfortunately all we have for information is the stamped marks on the blade ricasso. On the backside ricasso these are, the name "Culver" and underneath, "ARIZ.USA". On the face side is "SER #040". We have ascertained that it was not made by any maker of the same last name currently listed in our reference books. The blade is 1 1/4 inches wide and 1/8 inch thick. Hidden tang construction. The guard has some pitting and the blade has a couple of very minor scratches, but this is still a very practical using knife.
