This icon shows an outline of a fist up to the wrist. All of the fingers and thumbs are folded in to indicate that it's closed. There are lines on either side of the hand to indicate that it's shaking out of anger.
This Fist icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
