[2E] Uratha and languages

Fetish – Tongue Splitter (••)
This knife is splitting tongues – both physically and metaphorically. It’s often used in infiltration of foreign territory, by various werewolves.
Effect: Tongue Splitter let’s a user with Skin Thief Facet to cut a tongue of his victim with Splitter and then eat it. This marks a user to use all languages victim knew for one full lunar month.

About using of Tongue Splitter - Would it be Harmony Breaking Point? If yes, on what side? It's not killing of the victim. It clearly would be Integrity Breaking Point on level of 'Causing visible serious injury to a person', so -2 penalty? Or maybe -3 as Torture one?

Pondering on Harmony Breaking Points of using Fetish - it looks like it would be Breaking Point toward Spirit, as it is most the same as this from WtF 2E corebook:

Eating human or wolf flesh for Essence (–3)

Just change 'for Essence' into 'to get Fetish effect' and it's perfect fit.
