6265 Folding Hunter (1964 and later)
6250 Sunfish pattern (1964 and later; includes the 'Elephant Toe' w/etched blade)
You'll sometimes see them described as 'pakkawood', but it's the same stuff (laminated & stabilized wood). I'm pretty sure there are others, but those two are what come to mind at the moment (I have versions of each). Pattern numbers starting in '6' will be jigged.
(Edit: leafing through a collecting guide to find some more):
6217 4" 'Curved Jack' pattern (1970s; similar to the Swayback Jack in handle shape, with large sheepsfoot and a pen blade)
P172 'Buffalo' large clasp pattern; late '60s - early '70s, and my guide describes these as 'pakkawood' (think they were smooth; not jigged)
61051L 3-3/4" lockback (1970s - '80s)
C61050-SAB 5-3/8" Swell Center Hunter (coke bottle pattern; 1964 and later)
61011 4" Pruning Knife (1964 and later)
