Please help to identify time period of these two

Ideal seems to be domestic (I did not find a separate forum for that brand), somewhat cheap, O.M.O.R J-234 was clearly made in Japan, so just need time periods for both.

The Ideal dates from 1924 to 1986. I don't have a date for the O.M.O.R., but it looks 1960's to me.

I remember as a kid in the 60s noticing that some cheaper knives did not even have bevel on each side of the blade. Just one side. These were usually shell-handled cheap pocketknives.
