That is a good question for stamp and dating junkies.
For the patterns that followed that convention, Walden was dropped from the name, the stamp began in 1973, and it roughly ended in the mid to late 1970's. Maybe some patterns a bit longer, but it is difficult to track. There were a handful of the Open Stock folders (by Open Stock, not Uncle Henry and Old Timers) that has that stamp with the pattern number on the back side too, like a Schrade Walden NY USA style of stamp.
It is confusing, as I think for example, there were some new patterns that came out with a three lined stamp during that time period, but did not have the NY in the stamp. The 194OT and 94OT for example, first appeared in 1976, as did the 77OT, but I do not believe a 77OT ever had the three line stamp, and none of these three had the NY. The 61OT also came out in 1976, and it always had the three line stamps. The 194 and 94 changed to a two liner at some point.
It seems like the 33OT and 34OT may have kept the NY Stamp for the longest duration.
Similarly was the Schrade Walden NY stamping that began in 1946, in which all blades were stamped, and there were no pattern numbers. By the early 1950s, the Schrade Walden NY USA stamp replaced those, only the masters were stamped, and they started stamping the pattern number on the back.
I know, you asked me what time is was, and I'm telling you how to build a watch...

OR... did both types of tang stamps occur throughout 1973 -2004??
For a specific example
Schrade
NY USA
