My grandfather's WWII knife, US Army, Pacific theater. Captain, Major on his way home I think. He died in 1984, emphysema, in part because he got malaria in the Pacific. Fought in New Guinea, Mindanao, and at least one other island I can't remember. My older brother talked with him about his war experiences, and the quote I remember most is, "I landed on lots of beaches, and I never saw a Marine."
