Pair of old Old Timers. The 7OT is 1978 to 1986 vintage, with a 1095 blade. The "Schrade Plus" 858 Lumberjack stockman is from 1978 to 1984. I'm pretty sure the "Schrade +" of that period was 440A. From what I've heard, Schrade didn't make the switch to 420HC until sometime in the mid to late 1990's.
