I talked to a man today who said he had a buck 110 sp.ed 1981 etched with weiser lock on the blade, huntington beach. he said he had gotten it as a promo from weiser back then. I checked Levine's book ed #4 (very useful) it was not listed. I understandhe did not make that list. My question is can one assume there are more special editions out there that are not listed? Does someone have a more complete listing? Thanks
