Quadratic sawtooth is a sawtooth with a quadratic envelope, assembled by Martin Grant on May 7, 2015, from a design by Alexey Nigin based on a concept posted by Aidan F. Pierce and input from several other contributors.[1]

It consists of two caber tossers with period multipliers for timing, which activate and deactivate two toggle rake guns.

The gliders emitted by those rakes annihilate on the diagonal while the rakes are eaten by 2c/5 ships. All the rakes and gliders are destroyed before the next cycle.
