I have said this before and I'll say it again here. There is NO way to tell a knife's maker by the shape of the knife, and absolutely NO way to tell anything about it's history by the shield unless the shield has a maker's name or model on it which some do. There are a few unusual shields which were used by only a few companies, but the federal shield on your knife was used by hundreds of companies. For anyone to say it's a Keen Kutter or anything else is just idle speculation without being able to read the stamping on the blades. It is NOT a boy scout knife, they will have boy scout shields on them. If your knife has two blades it would be called a serpentine jack or sometimes a premium jack. The scales (handle covers) are celluloid which has been used for over a hundred years, so that is little help for ID purposes except for the fact that it appears to be glitter celluloid which was not used before 1900, but was popular in the 1930s. Rusted out pocket knives are some of the more common relic type finds out there, many, many thousands, likely millions were lost over the years, but sadly once they are too rusted to read the maker's marks most are unidentifiable. I don't know why some folks go gaga over finding them, I guess it's the old "one man's trash is another man's treasure" business.
