IMHO, the 154OT is a far underappreciated knife. And much more uncommon than one might believe. And I don't have to tell you that the Tractenberg knives are among the best preserved, most complete examples available.
An excerpt from my research on the 154OT:
The Schrade 154OT Drop Point Hunter is a uncommon classic Schrade pattern Old Timer fixed blade. The 154OT was the fifth fixed blade Old Timer when it was first introduced in 1976 (15OT-'64, 165OT-'67, 41OT-'71, 152OT-'73) and was produced for only thirteen years before being discontinued in it's original form. It was first manufactured after the Schrade-Walden name had been changed to Schrade Cutlery (in mid 1973), so will only be found with the "SCHRADE U.S.A. 154OT" tangstamp on regular production knives. In the 1976 Schrade Cutlery catalog it listed for $14.95 and simply called Drop Point, though in a magazine ad, it was called Drop Point Hunter. In 1987, the name was expanded to Drop Point Hunter in the catalog. It listed for $22.95 in the 1988 catalog (but could be found for less from the mass marketers). Oddly, I have an early woodgrain box (circa 1984) where the knife is called Drop Point Sharpfinger.
