> This page covers the **Knife brush** for sculpting in **Cinema 4D**. It pulls vertices together along the stroke and can lower them at the same time — producing sharp cuts, creases and incision-like details.

See [Pinch](https://help.maxon.net/c4d/en-us/Content/html/TOOLSCULPTBRUSHKNIFE-MDATA_SCULPTBRUSH_SETTINGS_GROUP.html.md) for additional effects.

The **Knife** brush pulls the mesh vertices within its area of influence together or – with the `Ctrl` key pressed – lowers them.

Pulling together and lowering can be controlled separately using the brush's settings.

An overview of all available brushes can be found here: [Brushes](https://help.maxon.net/c4d/en-us/Content/html/49929.html.md).
