When my second son got married, he wanted to be wearing the family USMC NCO sword, the rest of the groom's men carried sword canes. These were not very expensive, but a straight cane with a 20" blade, sharpened on 2 sides.
One dad had when I was young was a 28 or 30" tri-foil blade. Dad seemed pretty good with it! Who knew public High Schools taught Fencing in Phys ed. class in the 40's?
After I had my stroke several years ago, I thought I might have to use a cane for the rest of my life. I found canes to be useful to "redirect" impolite youths who were intent on bumping into me and thereby knocking me down (one good rap with the cane, and they kids stayed away from me! One lesson served all the boys at church!)
But while I was unsteady enough to need the cane, I wouldn't have had the balance to use the sword! Fortunately, I recovered enough to not need the cane, and I carry a J-frame instead! But a cane goes with the grey hair and mustache, so I carry when Holiday shopping and the crowds are thick!

When my sons and I need to put a better edge on long blades like cane swords or regular swords and machetes, we start with a steel wheel sharpener mounted on a Work-mate to get long enough single passes to do the entire blade length. And finish ceramic sticks the same way.
