Winds of Chaos

The subject is fairly self-explanatory, but for additional background, I am currently playing in an (all) Skaven Campaign and their is a Clan Eschin party member who was considering becoming an Eschin Sorcerer. According to the Warhammer Fantasy Wiki (or https://warhammerfantasy.fandom.com/wiki/Weeping_Blades), Eschin Sorcerers are the craftsman (or craftsrats?) that create weeping blade weapons through mundane and magical means, so tangible rules for such a weapon will almost certainly be relevant in the future, but I couldn't find them anywhere yet, assuming they exist. Do they, and if so, could you please provide the book and Pg #?

Thank you for your time.

there was errata for the skaven book which included it, and i happen to have retained a copy of the PDF. here's the excerpt relevent

"We didn’t include Weeping Blades in
the Tools of War. Should you wish to use them
we suggest that they should deal SB damage,
have the Defensive Quality, and counts as if
permanently treated with Black Lotus Poison
(WFRP 122). Using these weapons effectively
requires Specialist Weapon (Weeping Blades)."

I didn't expect such a quick response, thanks for the help!
