You'll thank me.
Whether or not you build things, or repair things... every household tool box needs a Grabit set.
We've all stripped screws before, or encountered one at the most inconvenient time (trying to put together a crib at 9PM with a cranky baby who needs to sleep NOW)...
Give yourself 30 seconds to cuss (not out loud if the kids are around, of course), grab the Grabit and get on with it. The Grabit stripped/broken screw extractor will have the bad screw out in seconds. It rocks. Trust me.
