>wall decorating katana for assisting water bottles fulfill sedokuBe careful. Cheap Katanas are notorious for sending people to the hospital. Even if you are following safe practices, a sharp stainless steel sword is a bad idea, they break often and can send pieces flying.
If you want to do some water bottle cutting, or single player larp (not saying I don't) consider using a cheap short sword, like a Schrade Priscilla (I highly recommend) or a Cobra Steel. If you want a Katana in particular, Ronin makes a fully functional, proper carbon steel, one for $130, that's as cheap as I can recommend.
pic related are my two proper swords. A Hanwie Raptor and Valiant Armoury Rhinelander.
