Fulcrum

Fulcrum is a special material that automatically generates Pivots.

Fulcrum only works when mixed with Rigid. It generates a frictionless pivot that does not need to be associated with a particle. This permits the pivot to exist at any location without physical interference.

Fulcrum is extremely useful for making things that need to be centered and round - mixing Rigid, Fulcrum, and Outflow produces a material that is capable of cutting round holes.
