Case knives dating system
The stamp that includes the word “Case” is the tang stamp.
Case has introduced 33 distinct tang stamps since 1905 for its folding knives, and 17 stamps on its fixed-blade knives.
The dots are a dating convention that the company introduced in 1970. The lightning S's are simply a design element introduced in 1980.
In 1970, Case added dots beneath the USA on the tangs of all knives. So, nine dots appeared in 1971, eight in 1972, and so on.And now, to celebrate the turn of the century, we are introducing a new tang stamp and dating system using a combination of Xs and dots to date the production of each Case knife.From 2001 through 2005, we will remove one dot for each year.From 2006 through 2009, we will remove one X each year. Case makes it easy, with a system of stamps, to identify a knife as an original Case and to identify it by its pattern, year of manufacture and composition of steel. (There may be one stamp on either side.) The stamps will be on the largest blade of a multiblade folding knife.
