The original form of 戣 (kuí) (a type of halberd);
The original form of 葵 (kuí) (mallow);
A measuring tool, conceptually related to 揆 (kuí). Cheng (2024) proposes it depicts a setup for measuring solar shadows (using 土圭 (tǔguī, “clay measuring rule”)) to determine directions and solstices, and also considers it the original form of 規 / 规 (“compass; rule”).
