>How can you tell the which models are government models?
you can go to theSOG collectors site and look at the Extraodinary Knives section. Starting with the Government there are variations and "decendants" that share the basic design.
>Will they be labled?
On the box, yes. On the knife, no.
>Or are the older seki japan ones all government?
No. Most of not all of the SOG fixed blade models were made in Seki Japan until about 2006, I think.
>And whats the WDM MA labled ones mean?
I think you mean EDM WA.
