Looking for Amazon sword cane for cosplay

As the title suggests I'm looking for a sort cane preferably not a real one I don't trust myself, I mainly want one so I could customize it and I'd prefer if it's durable, I don't intend on banging it on a bunch of random stuff but it's better safe than sorry. I know I probably could get a polyurethane (or some other plastic starting with Poly I don't remember the precise name) katana I'm probably make one using the sword and chief but I remember seeing a video stating that's actually rude to use a katana as a cane and I don't want to offend anybody. Let me know if you can think of anything in the comments.
