A couple years ago one of my customers (handyman) had me hang a mirror in her home, and gave me a type of hook I'd never seen before. Amazingly simple and effective: it was a large curved piece of hardened steel wire with a sharp point at one end and a hook at the other. One simply jammed it into a wall (drywall, not old-style plaster), pushed it through, and voila! a strong hook ready to hang stuff on.
I remember she said she got it at Home Despot, I think. Thing is, I've looked for these hooks since and have never seen them anywhere. They might have been advertised on TV as well. Had a catchy name like "Super Hooks", "Mega Hooks" or some such.
Anyone seen these? Know where to get them? I'd like to have a supply on hand. For simple tasks like hanging anything heavier than a picture on a wall, they're the best I've seen.
