The Frontiers are my "try to find knife" right now. I enjoy buying them and cleaning them up.
Larry, I will have to admit that one knife isn't a Frontier (find it). I never thought of the belt buckle until it was mentioned because of a post I did a few months ago.
Dave, the "P" series is a bunch of good looking knives. The sheath next to the P-IV is in good shape. Shows carry use but the knife didn't show any use.
The yellow Delrin and the stag ones seem to be the hardest to find on the bay.
On Larry's site there is a list of dates of manufacture of the knives and the yellow ones were only made in 1976 and 1977.
Thanks to all for looking. And I hope this thread doesn't raise the price of the Frontiers.
