Aluminum cans are also a possibility, but use of aluminum to make cans was only introduced in 1957, and I don't know when that invention found its way to the Philippines. In any case, I think the knife is probably older than the late 1950s/1960s.

Otherwise you are correct, the 1940s is also a very good guess.
