Nuh uh. There are lots of excellent alternatives. First, a cane sword is not a good idea legally or tactically if you are after self defence. Most of them are garbage in any event. I strongly suggest you look at Crawford's Survival Staff, and there are many options in terms of blades that aren't for this thread. Toxic Toys and others made some amazing indestructible stuff, and if you like thin and light, titanium is part whip part stick. Invredible stuff. You can get other canes too, like Crawfords, with interchangabe parts for when you need to change up sections or use a staff or travel. But, as the expression in the movie goes, there's nothing like a nice piece of hickory. There are lots of first rate guys making canes to your order and design, especially in the USA ( and turkey ) They can be very, very cool. In terms of self defence, there are whole parts of martial arts dedicated to cane and staff technique, especially Kuk Sool Won that has techniques designed for use with walking canes. So many better alternatives to a sword cane. The LEOs and customs are looking for that. Don't try.
