Duviri triggered my "amateur weapons nerd" in the best way, and I must share

[TheSixOfDiamonds]

As stated in the title, I find all manner of weapon designs fascinating... but am not an expert by any stretch, it's very compartmentalized (like how I've still not forgiven DE for the Kopesh longsword skin bending the wrong way, but have almost no clue about Norse swords). I was leveling Sun&Moon and realised some stuff at the same time (that I'm surprised too me this long):

1) Syam for players is a katana, but for Dax in Duviri it's a tachi.
2) Sun&Moon is a tachi&wakizashi combo, I never noticed this when Teshin used em, or for the whole Duviri Paradox quest.
3) Because Sun&Moon includes a Warframe-weighted tachi, we could get a straight tachi in the future, which makes me very excited (tachi is my second favourite historical sword behind the khopesh), and it might even come with its own stance.
4) Because Japan had very few standards for what classified as "katana" vs "tachi"... if you flipped the saya in the Arsenal (so the curve faced down), are WF katanas long enough to be tachi? I'm not sure how to measure them in-game.
5) We actually have a weapon in-game named after a unit of measure: Shaku. I find this very amusing. Shaku is a unit of measure Japan used for a while (katanas being 2 shaku minimum, odachi being 3 shaku minimum)
