ren+feng dao = REN4
Renzipang on the left is a person it means “man” and sounds like REN. On the right is a knife with a dot on the blade to draw attention to that part of the knife. It too sounds like REN! So this character obviously says “REN”. It means MEASURE because it is the idea of a MAN touching the Edge of a Blade to get the MEASURE of how sharp it is, to use the tool as a MEASURE of length too.
Baidu translates that as:
Benevolent people know the edge and shoulder their duties
