A multitool that weighs less than a penny? Yes, it exists. This video by [ToolTechGeek] shows his titanium flat-cut design tipping the scales at only 1.9 grams—lighter than the 2.5-gram copper penny jingling in your pocket. His reasoning: where most everyday carry (EDC) tools are bulky, overpriced, or simply too much, this hack flips the equation: reduce it to the absolute minimum, yet keep it useful.
You might have seen this before. This second attempt is done by laser-cutting titanium instead of stainless steel. Thinner, tougher, and rust-proof, titanium slashes the weight dramatically, while still keeping edges functional without sharpening. Despite the size, this tool manages to pack in a Phillips and flathead screwdriver, a makeshift saw, a paint-lid opener, a wire bender (yes, tested on a paperclip), and even a 1/4″ wrench doubling as a bit driver. High-torque screwdriving by using the long edges is a clever exploit, and yes—it scrapes wood, snaps zip ties, and even forces a bottle cap open, albeit a bit roughly.
It’s not about replacing your Leatherman; it’s about carrying something instead of nothing. Ultra-minimalist, featherlight, pocket-slip friendly—bet you can’t find a reason not to just have it in your pocket.
I would rather have the penny. The only multi tools worth having are the kind design for a very narrow set of similar purposes. i.e. a 7 in 1 screw driver.
For everything either carry the right tool or a decent pocket knife.
I believe all of the pennies I have in my pocket are copper clad zinc. If I had a copper penny in my pocket, it would weigh more than 3g… I suppose that just underscores the point that the titanium gadget is lighter, and presumably harder, than a penny.
when i was a poor college kid who had been raised by neglectful housecats (that’s why i am now completely self-sufficient) and riding a Greyhound to college, I discovered there is a place on the emergency exit door where a beer bottle can easily be opened. (Beer being an essential means of surviving Greyhound, even if it is officially illegal.)
