I have a small collection of Unit historys from WW2. It is interesting how many mentioned receiving gifts of sheath knives from local High School shop classes. I suspect that many knives listed as "theater" made are actually shop class made. I've seen documents of both the Army and Navy releasing obsolete swords to high schools so the blades could be used for these projects. I do not mean this as detraction in any way from the knife and any item that can be accurately attributed has extra interest.
