YouTuber ToolTechGeek has designed and created a titanium multitool which weighs just 1.9 grams, less than the 2.5-gram copper penny it is designed to fit in alongside your other change.
The tool, which is flat-cut via laser to ensure rust-proof resilience, includes aPhillips and flathead screwdriver, a makeshift saw, and a wire bender.
It also boasts a 1/4-inch wrench, a paint lid opener, and the ability to force open bottle caps and snap ties.
Although the gadget is not intended to replace a heavier-duty tool such as a Leatherman, its ultra-minimalist design means users are likely to find reasons to carry it everywhere, just in case.
