"It" appears to be an Manix -- here are the most basic facts --
Steel: claimed: s30v
Construction: pinned instead of screwed (perhaps I was the one who was screwed

Hhandle: grey FRN (I don't how FRCP feels, so I could be wrong)
Was such a knife even offered by Spyderco?
If these traits are not dispositive I will offer detailed pictures, if I am able.
One way or the other, good lesson learned.
