Gardiner sign listed no. U20, is a portrayal of the adze. It is used mostly in the cartouches
of pharaonic names especially, or other important names.
The adze on block[2] has the Egyptian language value of stp[3] and is the verb "choose". It is used as a determinative[4] in 'stp', "cut into pieces", and as an ideogram[5] for 'stp', "choose", "choice".
The adze tool sign, Gardiner nos. U18 and U19,
,
, portray just the adze, (or hand-axe).
Cartouche usage: "chosen of"
The most common usage of this hieroglyph is for a descriptor with the names in the pharaonic cartouche. An example for Ramesses II, shows his prenomen as:
UserMaatRe SetepeNRe, and is approximately: Maat's Power of Ra, (the) Chosen of Ra. (i.e. Maat's Powerful and Chosen (one) of Ra)
