I have a questions about early production runs. I own two knives that are stamped with a production number - a Boker A-F Combat Knife (stamped 559 out of an unknown production run) and a SOG Desert Dagger Special Edition (stamped 14 out of a production run of about 150). Obviously the DD is the more desirable of the two due to the reduced number of avaiable units. What I'm wondering is this: Is the stamp on the Boker just a marketing gimmick (as a marketer myself, I'm always on the lookout for marketing ploys), or is it part of some sort of limited production run?
