I saw an internet auction for a Spyderco Chinook today. The auction references the photos for questions about the place of manufacture.

The photos show what looks like a Chinook, and the Spyderco logo is stamped into the clip.

The strange thing is that there appears to be no place of manufacture nor blade steel designation on the blade. I recall that some models of the Chinook had the James Keating logo added as well. This one has nothing.

Does anyone know if Spyderco ever released any sterile Chinooks?

Maybe this one was a production prototype?
