What are some weapons for 1/12 scale, besides Little Armory?
They can be Medieval, Fantasy, Modern, etc..
While technically 1/10, most Mononofu stuff fits either NECA or Marvel Legends stuff pretty well. Beware though when it comes to katana, because Mononofu made both 1/6 and 1/10 scale Katanas.
There were a bunch of other Japanese blind box weapons
Dragon Quest, Monster Hunter, and Onimusha 3. Most of them were made by Boford Japan I believe.

Here's one of the regular Katana from the Onimusha set.
And here's a Mythic Legion with some sword from Mononofu.
Some people say that for fantasy/melee weapons, larger looking still wouldn't look that bad, but you be the judge.
F-Toys have a katana set.
