This Tiny Titanium Whistle Is Smaller Than Your Fingertip but Screams at 110 dB
YSMART has taken its obsession with miniature everyday carry gear to the humble whistle. Measuring just 2.9 cm long and weighing 3.4 g, the titanium WhisTi produces up to 110 dB of sound while doubling as a micro pry tool. There’s also a wider Dual version capable of 120 dB.
