Good price for 3 swords, though they are most likly knock-offs of some other brand, if you enjoy them, then im sure it was worth it. I found this about 440 steel...
sword site wrote: 420, 440A, 440B, 440C, 440V, ATS-34 - Stainless steel. Great for kitchen knives, folding knives, etc. Sword-makers such as Gladius and Marto/Martespa of Spain use it a lot. However, they are unsuitable for swords and swordplay re-enactment, namely because of the weak grain boundaries caused by the presence of the chromium, which is used as a grain enhancer and gives it it's "stainless" properties and mirror finish when polished, but makes it more brittle. Chromium and other alloying elements like Vanadium, tungsten, etc. can make steels stainless, fine grained, heat resistant, etc but really add to the problem because you cannot create a beautiful hamon ("cloud pattern") line with these steels. The ones that appear on replicas are ugly acid or electro-etched sine waves! NOTE: Some rip-off companies only put "440 STAINLESS STEEL" on their products, but neglect to say whether it's 440A, B, or C. Since 440C is the most qualitative of the lot, they just say "440" and lean on the popularity of 440C, which is dishonest.
Good thing is that its stainless steel and wont rust like regular steel. If it has a mirror finish, it will be hard for rust to form, and easier to clean aswell (or so Ive heard). Though you should still take care of it. Wipe the blade often, and it might be good to buy a bottle of oil for it, or ren wax like anduril101 suggested. Congrads on your purchas
