Apart from the obvious uses, I’m finding the crutch an invaluable tool while I am house-bound.
I can whap spiders’ webs.
I also discovered when friends came to cook me dinner (fabulous) that it was a useful pointer. “There are the dishes” “There’s the salt.”
I know it’s also useful for holding open doors and I reckon it’ll be useful to trip up small persons who run unseeingly before me when I’m out in the big, wide, magical world.
