Fight'n Rooster does not have a "Tang Stamp Chart"
Actually the Fight'n Rooster Knives only have three (3) different blade tank stamps throughout its entire production run.
One cannot know what actual year his/her knife was made, only a grouping of year runs, with the exception of course of some master blades having a production date, and many having this date often with how many were produced.
The first stamp used on Fight'n Rooster knives (rear tang) was Frank Buster Cutlery Company Germany. The front of the blade was stamped with the two Rooster Trademark and the word Solingen underneath the roosters. There was no wording above the Roosters.
Used from 1977 - 1982.
In 1982 the rear tang stamp was changed to Frank Buster Celebrated Cutlery Germany. The front stamp had the words Fight'n Rooster added above the two roosters.
The vast majority of Fight-n Rooster knives have this stamping, and are known as (Celebrated)
Used from 1982 - 1994
The rear stamp was changed in late 1994 to Frank Buster & Son Celebrated Cutlery Germany. The front rooster stamp did not change.
Used from late 1994 - Through last production.
You may occasionally find a Fight'n Rooster knife with a different tang stamp, but it is not common, and it would not necessarily increase the collector value.
It's always important to know what you don't know.
