The "Bite-Across" as an Anchoring Symbol

The "bite-across" seems like an anchoring symbol (previous post: https://www.facebook.com/share/p/1CB6jCGhfr/ ), and here are more possible equivalent symbols. I suggest this because they can sometimes be found together to reinforce that meaning.

A sword, spear, staff, lance penetrating a neck, is not only a flow connection, but sometimes it appears to be an anchoring downward compression. A shackle on a chain also seems to be anchoring and sometimes as an upward pull/tension on the chain, as well as chain being a high-density flow symbol. https://ca.pinterest.com/stevenbhalls/chain/ https://ca.pinterest.com/stevenbhalls/shackles/

A foot compressing a body part. Not only is the foot a portal symbol, it may have an anchoring aspect. Maybe portals (which are vortices of half-a-torus) need to be anchored to the barrier. If ancients thought that a portal needed to be anchored to it's barrier, that could explain why the shen ring (a portal/inlet/outlet symbol) is rope-lashed to its barrier. https://ca.pinterest.com/stevenbhalls/shen/
