He says "I can fix that" before he fully knows what "that" is. The dishwasher, the deck board, the light switch that's been sparking a little — he's watched the video, he's got a theory, and he is going in. Sometimes it works on the first try. Sometimes it works on the third try and a second trip to the hardware store. Either way, he never calls a guy, because in this house he IS the guy.
The hard part of shopping for him is that he already owns the basics, and he buys his own consumables — the drill bits, the caulk, the box of drywall screws. What he won't buy is the upgrade: the pro-grade version of the tool he's been limping along with, or the comfort item that feels like a luxury when there's a project to fund. That's exactly the gap you're filling.
Below is a spread — everyday-carry stuff under twenty-five bucks, the mid-range tools he covets on the shelf, and one or two splurges he'd never green-light for himself. Match it to whatever he's currently elbow-deep in.
