Swordcanes are very illegal in the UK, that one's a bad idea as almost none of them are subtle enough to get very far. Personally I recommend this, mine's never even been scratched or warped and I've had it for the best part of a decade now. Plus it has the added bonus of shillelaghs being an irish fuck you to english weapon restrictions.
