You don't hide a katana. You carry it in its sheath at the waist. The good thing about the katana is that it's a very sharp sword that is folded hundreds, even thousands, of times during its forging to make it very strong and it is also quite light and very easy to handle.

He should have used a chainsaw. Then he could have screamed "WHO'S LAUGHING NOW?! WHO'S LAUGHING NOW?!" as he did it.

.....i think a samurai sword is bad enough....

Pussy... real men use chainsaws when beheading their relatives.

Yes so instead of getting a clean swift swipe, and getting off their head, you use a chainsaw, which carves them up, and gets a shti load of blood on you. Yea that woudl be great, explaining why youve got blood and body parrts on you to anyone you may see. The samurai sword would be a much cleaner approach.

You want clean? Incinerate.

Incineration would still leave fragments of bone and hair which would be found by forensic investigators. I think the best approach would be to use poison. Something household that could easily be consumed with few side effects. Few people would suspect it was you...although they would still have their ways of catching you, maybe.

I am not withdrawing my statement. I want that mess.
