Someone who is cackhanded is lefthanded, and hence a clumsy fool who can't write or use a knife and fork properly.
My sister is cackhanded. It's really annoying because you can never find righthanded scissors in the house despite the fact that 3/4 of my family are righthanded. I'm sure she chucks them away as a result of her bitter twisted resentment of the fact she's not normal.
