With regards to flaming swords, yet another splendid example may be viewed in our Nation's capital, as presented below.

Within about 90 days of the correspondence above, the United States Army issued the following "Letter Requirement" specifying desire to have an impact resistant, modular bayonet hilt:
SPECIAL NOTE: PLEASE NOTICE ITEM 6. (BOTTOM OF PAGE/"TECHNICAL ASSESSMENT") CLEARLY PROVIDES THAT "STATE-OF-THE-ART" TECHNOLOGY IS AVAILABLE, FOR USE IN THE PREFERRED BAYONET.
