This Gerber knife is pre-owned in excellent unused condition. There is no wear on blade or leather sheath. Don’t have original box or paperwork. PC1: PRESIDENT’S Collection TYPE 1 : “PRESIDENT’S COLLECTION”; MARK I AND MARK II WITH MATCHED 4-DIGIT SERIAL NUMBERS; ZEBRA WOOD; 440C STEEL; WIDE WASP; HIGH POLISH; NO TEETH; PLAIN BRASS GUARD & POMMEL; SLANT 2 LOGO. The PC1 Mark II knives have the wide wasp waist blade profile with a mirror polish and no serrations. They have a three part handle consisting of a solid brass guard, a central Zebrawood handle and a solid brass pommel with thong hole. There are three narrow spacers at each end of the handle between brass and wood. The spacer colors are red-white-red. These are very special Gerber Mark I and Mark II knives. They are hand made by our most experienced craftsmen using the finest materials available. We are proud of them and hope you are too. The steel is 440C Stainless, the very best! It is hardened to 57-59C on the Rockwell scale. The handles are Zebrawood from West Africa. All brass parts are precision investment castings. The PC1 knives are found on 1979 to 1983 knives in the observed serial range of 0035 – 0775. It is assumed 1000 sets were made. WARNING: Use extreme care if attempting to clean the brass guard and pommel. Keep all polish off of the wood. The dull patina that forms on the brass is “verdigris” (copper acetate) and will stain the pores of the wood handles a green color. I hope this helps.
