The London-based outfit YSMART seems to have an obsession with shrinking everyday carry gear to ridiculously tiny proportions. Flashlights, knives, pens. You name it, they’ve probably tried to make it smaller. And now, the humble whistle is getting the same treatment.
The YSMART WhisTi Tiny Titanium Whistle not only makes this safety/survival EDC tiny, but it also throws titanium into the mix. So, yeah, there’s no worrying about your whistle being destroyed by nature or bears, or moose if you are in Canada.
Measuring under 3 cm (2.9 cm, to be precise), or 1.18 inches, this Grade 5 titanium whistle may be tiny, but it’s no slouch when it comes to making a din. YSMART says it is capable of producing up to 110 dB, increasing your odds of being heard in the wilderness.
But this wouldn’t be a cool EDC if it only whistled. It is also a multitool of sorts, bringing to the table a micro pry tool you can use to pry things, lift tabs, and open packages. It is no larger than the distal phalanx of an adult’s index finger and weighs just 3.4 g. It features an easy-blow design that produces a distinctive sound (ear-piercing, if the video’s sound is accurate), all wrapped in a sleek, faceted shell.
If 110 dB isn’t loud enough for you, YSMART is offering the Dual, a double-width version that screams at up to 120 dB.
The YSMART WhisTi Tiny Titanium Whistle is, of course, keychain-ready, and being titanium, it is resistant to corrosion. So yes, in case you find yourself in an unfortunate situation like Chuck Noland, this whistle will survive the elements. Though I doubt whistling on an uninhabited island in the middle of the South Pacific Ocean will attract any attention. A passing ship, maybe. But what are the odds without first riding the waves, as Noland could attest?
The WhisTi is currently being crowdfunded on Kickstarter. The campaign has met its funding goal, and so the product is a go. If everything goes according to plan, deliveries should begin in March 2027.
If you’re down, you can score the WhisTi at 30% or more off on Kickstarter, with pledges starting at £24 (or about US$32, according to Kickstarter).
