Hiya Sid!
I just checked out my AMK Shadow.
It is marked in the following manner:
Side one of the blade, dead center, 1/8" from the handle is "SEKI-JAPAN", stamped in black.
Side two of the blade, on the left side of the blood groove, approx. 1" from the handle is "AL MAR", stamped in black. To the right side of the blood groove is Al Mar's "chop", stamped in red.
On both sides of the handle is a silver medallion with Al Mar's "chop", blind engraved.
I don't see any serial number at all. I got it in the early to mid eighties.
Hope that enlightened.
VG FOR PREZIDENT, DAMMIT!
