Proposal to symbolize the center of gravity of objects
Simple improvement of a standard
These simple solutions are an extension of the symbol used in industry for specifying the center of gravity of objects (that looks like the one in the middle in the picture above).
One important improvement could be to add these symbols more frequently on objects that are usually carried in a way or another.
I designed it to be possibly engraved on metal or wood or plastic or glass without having to rely on the green color.
One important thing to understand in the systematic use of these symbols is how it can help prevent accidents and wounds, especially by repetitive gestures that have to compensate a non-optimal catch.
