Whats the most useful tool in your garage that most people don't think to buy

[Ridge]

A genuinely good stud finder changed my whole relationship with home repairs, cheap tool that's saved me from countless mistakes since I finally bought a decent one

Curious what people's own underrated tool actually is, the thing that isn't on most beginner tool lists but genuinely should be

[Western Depot]

A decent multimeter, most people don't think to buy one until they actually need it, and by then it's usually a genuine emergency

[MegaNathan60]

My moisture meter for wood, underrated tool that's saved me from several bad furniture purchases and repair mistakes over the years

[Solo Buffer]

A magnetic tray for holding small screws, sounds trivial but has saved me from losing hardware more times than I can count

[ArmandoCardoso]

A quality set of precision screwdrivers for electronics, most people only own the basic large sizes and need the smaller ones eventually

[ElectricVector]

A quality set of allen keys has saved me more headaches over the years than any expensive power tool I own

[Reward Dragon]

A laser level, seemed like an unnecessary luxury purchase until I actually used one and realized how much time it saves on any hanging or alignment project

[Kev49]

Best would be a good headlamp specifically, freeing up both hands during a repair has been more useful than almost any other single tool purchase I've made
