Kuma Kuma Kuma Bear - Ch. 112

[Dragou]

Maybe? That's certainly a benefit of the outcome, but I think the restriction is more due to Yuna being lectured by Fina on the value of mithril. From Yuna's POV though, the knife is effectively free (she has more mithril than she needs, has no real use for the rest of it right now, and she got the production cost of both in exchange for one of her huge stack of iron golems.)

Equally, Fina could have carried both in her magic bag, and only got out Shuri's if Fina felt it was appropriate/necessary. Even Fina only uses her mithril knife if she needs to, otherwise she uses the original Iron knife she had when she first met Yuna.

she has some mithril, but its clearlynot THAT much ... the "mithril-golem" she has is only coated in it ...... In fact she could make 2 skinning knifes and 2 daggers, the mithril she has left shouldnt be able to be used for much more, because it was stated it wouldnt have been enough for the knifes and a sword (which means the daggers were basically the limit)

She is just way too rich. XD
I personally dont think that yuna would have given Shuri the knife and then let her play around with. The result of Fina her scolding made it so that the Knife remains at yunas place and is only lend to Shuri when she uses it. Which is a thing/nuance that seemed to have gotten a bit lost translating the novel from Japanese.
Scolding still somewhat valid because its a bit too valuable for a kid as old as Shuri and not beeing a noble. (the point that Fina believes Yuna is too irresponsible with money comes from Fina beeing too poor first and them not understanding HOW FILTHY RICH Yuna actually is .... the author mentioned once that she would be able to buy several countries by their standards)
