The L3CollisionDeformer from our L3Deformer package is a very powerful modeling tool when used with the static dynamics feature. This mode allows you to sculpt geometry interactively by transforming attached colliders. All collision deformations are maintained unless you go back to the specified start frame, where the geometry is reset to its original state.
Using this method you can build kind of a stackable sculpt history by animating colliders with Maya's standard animation features.
In the example shown below we applied a simple spiral motion to the collider to cut a screw thread.
This is a very powerful way of creating reproducable sculpt effects. You can use ANY polygon shape as collider and even morph colliders over time e.g. by using blendshapes.
See this link for an animated GIF showing how the sculpt effect works.

Please note that the edge flow of the base mesh does not align with the screw's thread direction. Usually this creates jaggy artifacts. L3CollisionDeformer includes a very effective relax algorithm with lots of user controls to even out polygon spikes.
