10 March 2020: AmiAmi sells swords online
I'm not sure what use a 15-centimeter die-cast anime sword made out of zinc is, but if you ever wanted a scale model anime sword, I guess this is your chance. Maybe use it as a letter opener? Those of you who still get letters, at least. Anyway, this is not an endorsement of AmiAmi in particular, although I do order from it on occasion. It's pretty likely you can get these from other vendors. Besides, the available selection is not particularly deep.
I can't deny that I could potentially be interested in gimmick merchandise of this sort if it turned out the quality is reasonably good. As anime swords go, I expect that would require making them out of steel instead of zinc, but I imagine that would probably raise the price considerably. As it is, fifty bucks for a six-inch zinc "sword" is pretty steep, especially since I don't see any indication they come with display stands or whatnot. I am, however, quite amused that Sakura's key qualifies as a sword in this context. I have to admit that's pretty sweet.
