Daniele - The #25 with six inch blade has an "Antique Gold Micarta" handle.  I did not buy the knife new from the Randall shop, but when I got it, the knife still had the original shipping box and wrapping paper.  The white butcher paper has the notation "AGM" on it (among others) which I have assumed to mean Antique Gold Micarta.  Since the handle material on the five inch knife appears to be the same, I have assumed that it, too, is Antique Gold Micarta.  I don't know when the knives were made.
