Hi Mark,
Welcome back! and I hope all is well.
I think its pretty hard to really date modern items, but I know that there are books that provide some good data, one that comes to mind is Levine's 1995 guide. Also "Knives and Daggers" by Faktor (cannot recall publ date). is pretty good with knives like these. I suppose mostly the manufacturer data on the blade is usually best in the manner it is stamped and wording etc.
Otherwise the knife magazines are a great resource and often a letter to the editor can offer great information.
All the best,
Jim
