Unless a gizmo comes with an elf to run out and fetch my scissors from wherever I left them, they wouldn't do me much good.
I have 5" scissors and thread snips at the machine, 2 pairs of shears for cutting, one pair for the ironing board, one pair for paper, and I plan to buy another pair of 5" and another pair of snips to keep next to my chair in the living room - where I prefer to hand sew. I'd honestly feel sorry for any elf that had to try to keep up my forgetfulness.
