Push a screwdriver through one side and the tip holds screws. Push it through the other and it releases them. That's the whole tool, and it works exactly as described.
You're giving something that sounds trivial and genuinely changes how someone works, which is a rare combination at under twenty dollars.
A magnetised tip means screws stay on the end rather than dropping into wall cavities, gaps behind cabinets or down the back of whatever's being worked on.
The demagnetise side matters too, because a permanently magnetised driver picks up every bit of swarf and filing in a workshop and becomes a nuisance of its own.
It works on screwdrivers, drill bits, hex keys and most small steel tools, so one tool covers everything in a pouch rather than being limited to one driver.
You'll want to keep it away from phones, cards and anything else magnetic in the same pouch. It's a strong magnet in a small housing, and while it won't do any harm to tools, it's worth knowing before it goes in a pocket with a credit card.
It's a favourite among electricians and chippies, which is the endorsement you want for something this specific — these are the people losing screws into cavities daily.
It's compact enough to live in a tool pouch permanently, and at this price you can add it to almost any other gift without thinking twice about the cost.
If they've never used one, mention what the second slot does. Plenty of people magnetise a driver and then wonder why it's suddenly covered in metal filings, without realising there's a way back.
