On Cool Tools, Zarko Vujovic talks about Ikea's adjunct to a tack-hammer, a free gizmo that does the trick:
I am an engineer, so I admire the way Ikea consistently uses a small set of fastening systems, all suitable for untrained labor. Ikea has even invented this tiny plastic device to protect customers from smashing their fingers with tack hammers.
A pinch of the clever friction-grips opens a small crevice in this utensil, and it neatly grips any small nail. Place it against a wall, tap the nailhead, and the nail goes in quite straight. Remove it and you are ready to safely hang a picture. The ergonomics are brilliant, the understanding of process is good, the operative results are excellent, and many innocent fingers go unsmashed. A real triumph of Swedish design!
