Well, "I" (I have a charachter that is me, literally, in my story I'm writing) carry a pair of cane swords, sharpened down to a near atomic edge, one with a dragon head grip and mahogany wood cane with a very thin single edged blade and the other a cane made of ebony with silver flecking and a Onyx orb on the top (pommel), and this is double edged, rapier style blade. Both blades are made of a fictional metal, tho so they're extra strong.
But..... both could be made using high quality spring steel, and still be feasable weapons, so thats why I like them.
