Do any of the SOG ..hierarchy know anything about a knife with tang stamp EXPLORER 11-504 ..one side and 440 stainless Japan..on the other.The knife is drabb..olive green w/ black rubber handle .In the center of the handle is EXPLORER in a circular pattern just slightly larger than a pencil eraser.This kinfe is SOG SEAL..exact size , pattern, everything except a different pattern rubber handle.......and of course EXPLORER....Anyone know about these knives,I got it about 3 weeks ago ,but it looks to be new...not years old anyway.I've got to learn to post pictures,I've been born 100 years to late and am being dragged into 21st centry screaming and cussing the whole way,sorry no picture.
