Antique Sewing Tools Carved Bovine Bone Drizzlers Hooks Lace Tatting Crochet

Description

Antique Bovine Bone Sewing Tools
Provenance - Estate sale find in Western Pennsylvania
I am not an expert on sewing tools, so it is my online research that I am relying on.
My online research seems to indicate that the scissor like tools are possibly antique drizzlers or thread pickers.
The drizzlers have carved fists at the top.
The drizzlers also have carved symbols on the shafts. Not sure what these mean, or their origin. I will be happy to add info to this listing if anyone can help out here.
The drizzlers' "scissor" parts fold up like pocket knives and slide away into the shafts.
The hooks are possibly for crochet or tatting.
Please note - one of the hooks is broken at the top.
Please see the photos.
The ruler is for reference and not included.
