A hoe is a gardening tool, with a long handle and a flat transverse blade; it’s used for weeding, loosening soil, and so on. The hoe (called Haue or Hacke in German) is a period charge, found in the canting arms of Heügel and of Häckel zu der Altenstat, 1605 [Siebmacher 63, 95]. The hoe’s blade is to base by Society default, which appears to be the opposite of the medieval default; the illustration shows a hoe inverted.
