The Everitt Knife has been documented to WWII, there is no doubt they were around during the war. However, no one is sure who made them. I have owned maybe 20 of these knives over the years. They came in 2 colors, black and green (my green example was used and is missing the original blade finish found on the minty black example) with a riveted sheath. 1 opinion is that they were made in the USA, another is that they were made in the south pacific, mainly Australia. The double edged 7" blade with fuller and Aluminum handle make this a very light fighter. If anyone knows about the maker of these, please let me know.
