Buck Knife Date Codes
The 1973 to 1985 production knives bear a model number as well as the BUCK and the U.S.A.
In 1986, a year mark was added on the tang.
Following is a chart with the date symbols for their year.
No date symbol means the knife was made before 1986.
There is some additional coding for knives made between 1974 - 1986:
2005 - If it looks like Idaho, then it was made in Idaho.
2005 - If it doesn't look like Idaho, it was made overseas.
The latest tang symbols are arrows:
An arrow pointing down toward USA indicates 2007.
An arrow pointing up and away from the USA means 2008.
