Gerber Mk I Knife Information:
Accurate records on MK I serial numbers relating to dates were never kept (like they were with the MK II), but here is some information that will help with an aproximate date for any Gerber MK I knife. 1976 � 1981 blade composition was comprised of Special Alloy (L6) Tool Steel 1976 � 1980 blade length was 5� 1981 � 1997 blade composition was comprised of High Carbon Surgical Stainless Steel 1981 � 1997 blade length was 4 �� The knife was roughly 9� in overall length Rockwell hardness of 58 In 1984 a blackened blade variety was offered in the Mark I (Model# 5604). Knives that have an "XX" in the serial number or a "CS" are reproduction and commemorative knives. They are true Gerber products but the values should be adjusted accordingly as they were not made in the same years as knives without the CS's or XX's in the serial numbers. There is an "S" in the serial numbers of the stainless models. CS stands for "Cutlery Shoppe". 1989 was the First year of the Cutlery Shoppe knives.
Editors note: after a little research, here are my findings on getting rough dates from serial numbers. If you have any additional information to add to this article, please |
