The online community of knife collectors, A Knife Family Forged in Steel
For collectors, all Mark 2's produced after WWII are considered reproductions (of the original WWII) even when made by the manufacturer who made then during the War. This is not done to belittle new production knives.
You can tell current from WWII production by checking out the maker's mark on the blade. Current production (after WWII) knives place US over the manufacturer's name.
