Hi rwads3 from Australia,
Those blades were left-over blanks from Imperial Schrade, intended for their 2003-04 production.
They were sold at the Schrade Close-Down Sale.
A large number of them were then sent to China, to be finished off with poor grade wooden handles.
They were then sold off on eBay as "New U.S. made Schrade knives", some even sold in genuine Schrade Boxes.
The bone handled knives below, were made about 2002-03 by Imperial Schrade, as a special order.[hard to find now]
The 2004 Wooden handled, 100th Anniversary knife set, never made it to production.
Codger, has a boxed Sharpfinger from the 2004 Wooden handled, 100th Anniversary knife set
The knives below, were made up in China, using unfinished left-over Imperial Schrade blade blanks.
Note: The wooden handles, fitted in China - and the Genuine Schrade box, to deceive buyers.
The made in the U.S.A. paperwork, would fool buyers - unfamiliar with the original Schrade knives.
This is another Schrade blade, finished off in China.... Ken.
This Schrade Blade, is listed on eBay as a new "U.S.A. made Schrade knife with box"
