I think we have the definitive answer now. Both are correct with the blue flame being earlier and the red an official modification. Thanks to everyone for finding the answer, good job.  

Hi JM,   Some pics of the "home made vengeur". This one is to pay a tribute to a young second-lieutenant of the Third "bataillon de chasseurs à pied" killed in august 1914. The blade of the knife is protected by a wooden sheath  in the leather scabbard. The same thing for the "trench knife" already posted.   The portrait of this second lieutenant has hung on my office wall since my childhood. He was a relative to the old lady who took care of me.   Dominique

It is my understanding that 'Kutmaster' was a trademark implemented during the war but it was only on paper, it was in the immediate post war years that the branding as we see here was applied. I've been operating with all knives, folding and fixed, that are stamped Kutmaster as post war. 

FYI, Westmorland is spelled incorrectly should be Westmoreland.    Scott

luftaga1 the pleasure was all mine. thanks for your patience in the matter

That DOE badge is a generic style I have never seen used in the U. S. federal world.

Most all of those are a $1 to $3 at the shows and you wont end up with 3 of the same patch.  Good luck! 

Thanks for posting that badge, EE87. It looks to me like “NNSA” is the acronym for “National Nuclear Security Administration”.

Thank you dmar836.  

These were also in Air Force kits and flight suits for cutting parachute lines if hung up. Not very well made but really neat and for some reason people pay decent money for them. A friend offered me one of his from his VN era service but I just haven't mentioned it to him again. $20? I'd buy it too!
