We'll let you in on a little secret for this one: Every DIYer wants a power drill. This even applies if there's nothing to use it on. Right now, there are people all over world remodeling bathrooms in houses, tents, submarines and ice caves, and they would all love a top-notch cordless drill. Don't let the practicality fool you -- this is no boring-as-underwear gift. Throw in some extras like a magnetic screw holder, a spare charger or a 180-degree swiveling head, and you may even see some grateful tears during the unwrapping.
Sledgehammers also have some gift potential. Widely regarded by DIY remodelers as the most fun you can have without a chainsaw, the trick to finding a good sledgehammer is to one-up the classic model. For instance, some wrecking bars can pull nails, rip through flooring, smash walls like a demolition ax and even double as a chisel.
And while tools are great, don't forget about tunes. Nobody likes to work in silence, and a high-quality job site stereo that can take a beating is a welcome addition to any tool set. Just make sure it's tough because it will most definitely get splattered with paint, kicked around and covered with sawdust. But that's a small price to pay to hum along to "Another One Bites the Dust" as you rip out old tiles.
