hey guys i answered my own post. i posted a few days ago about pat nos. after just a little bit all of a sudden i found this.
http://www.google.com/patents?id=-2daAA ... dq=2170537 i have that knife with that patent no. this is an awesome new way to at least help date older knives. of course you cant date knives of patents alone since some of these patent are for improvements on previos models.but if you look hard enough at diagrams you can even better date your older usa knife by looking to see if it has the improvements mentioned. http://www.google.com/patents just made knife collecting even more fun for me!!!! let me know guys if anybody out their found this useful.take care in the link the last few digits are the patent no.
