I recently acquired a very unique Schrade knife. I am pretty sure that it was one of the last Schrades to leave the Ellenville factory, even though it was not accompanied by a certificate from Smokey to prove it. As a matter of fact, I would not be surprised to find out that it was one of the very last to be stamped out from the dies. I almost (but not quite!) regret that it is so unique that I may have to collect the more common varieties of this pattern to display with it.
As a former manufacturing process engineer, this knife holds a special allure to me. I can almost write the process sheets from looking at this knife and a regular production knife from my collection. I may very well attempt to do just that as an exercise in historical archeology. Obtaining an original set of production process sheets may well be impossible, but maybe not. If they could be found, it would be very interesting to see how my process design compared to that of the Schrade engineer's design. I will produce a set of blueprints as a required part of the process sheets. That too would be interesting to compare with a set of originals.
Some of you have mentioned that you received blades with a poor, rough final grind. This knife did not receive the final grind. None.
I also have heard of some the last Schrade knives having the scale rivets driven too deeply, and some with poorly fitted scales. I would guess that some, if not all of these knives were shipped out as seconds. Mine has neither rivets nor scales.
I have heard of Schrades with off center primary grinds and poor polishing. This knife is not ground or polished at all. The only process it went through after the blank stamping press was to have the tang stamp applied. It does have the rivet holes and thong hole punched. This may have been a seperate operation from the blank die operation as it looks like the holes were punched from the opposite side as the die operation. It is a rough, tangstamped blank. It did not even go through the flat grinder, as the outer edges are still flanged from the press that stamped it from the flat stock.
It is the most unique 152OT Sharpfinger I have ever seen, and indeed, a pattern collection will be built around this stainless blank!
