Usage of Hand Icon
The hand icon is an abstract but versatile icon if you have a good imagination. It can be used for a few purposes. For example, you may want to use it for sign language tutorials and articles. It would be great on anatomy or medical websites. It could be used to let users or readers know that a project is hands on.
