It sounds more like current production knives made in China, not something made in the Schrade factory in New York.
Do you have a link to where one was posted? I haven't seen a lemon yellow Sharpfinger unless it was a custom.
I have been all through the Schrade catalogs but do not recall seeing a lemon yellow Sharpfinger.
We are talking about Schrade so anything is possible, I have just not seen it if it is one of the American made ones.
