Iron
Options ToolIron
If your mesh looks too uneven, smooth it out using this virtual iron. The tool works in all three modes (point, edge and polygon).
The Iron tool works by smoothing out the selection in areas where the angle between neighboring edges is equal to or greater than a threshold angle (Angle). The strength of smoothing is controlled by the Percent value.
To use the Iron tool:
Drag in the viewport to vary the Percent value (i.e. the strength of smoothing).
