Go to page 43 and look at the illustration first. There is a symbol in the upper area below the eye symbol.
This symbol has both a split end (see Avry's post) and an angled end which is reminiscent of both the head of Thoth's staff and the Spinnecrock. The unknown symbol does not belong to Gardiner's D series, e.g. D36-D45. Junker in a very meticulous and detailed linguistic analysis with which I won't bore you concludes that this symbol is a logogram and means "weave". Junker further argues that the pronunciation of this logogram was probably "shesep".....The word shesep btw also means "statue" and shesepu is "Sphinx".
So what we see here is exactly to what Thanos and Avry already alluded. Even in DynIV the original inspiration which gave rise to this symbol is lost and the symbol persists as an icon of the original. That is exactly what you are looking at: The icon of a long-lost (tribal; primeval) object which gave rise to the shape of a tool because there is a common semantic root....ie for example ram and wool.
Addendum: Importantly, I forgot....shesep also means "palm" and the symbol for palm is a crescent moon which also of course means "jah" ie Moon. This is the phonetic link to Thoth! In other words the very same sound shesep meant weave and palm. The symbol for weave resembles the was sceptre, which Thoth holds, and the symbol for palm is identical with the symbol for the Moon...and the Moon was Thoth. I can document this at length citing Rolf Krauss, if there is anyu doubt about the Moon-Thoth duality if necessary.
