I remember being caught out by the Finesse in The Stonecutting knife, as Finesse is an arcane ability. I think that knife is the only example of an item using finesse. I'll try and find the post where someone pointed this out to me...

[Edit] It was here:
[url]https://forum.atlas-games.com/t/finesse-rolls/9218/8], on a general discussion on finesse. i'm still not sure if a grog ussing the knife could get exposure XP in finesse without having some teaching to 'kick-start' the process.
