Hoping to get this thread back on original topic/intent. viewtopic.php?f=4&t=39799#p386211
If you have information and examples of a maker's stamps and the dates when they were used, post them here. If you have a question about a particular stamp, and can't find it already posted here, please make a new post with your question in the Knife Q&A section, or the brand-specific section, whichever is more appropriate.
Thus thread is for posting reference material, not Q&A. Thanks!
