OKNIFE Owhistle 2 Ti Multifunctional Emergency Whistle
Constructed from lightweight, corrosion-resistant TC4 titanium alloy in a sandblasted finish.
2 Tools in 1: It functions as a whistle and a compass.
Dual-tube design makes the whistle louder and lets it reach up to 100+ decibels at a 0.5-meter distance.
Built-in compass with 10-degree increments is ideal for navigation and orientation.
You can change the color of the titanium surface to your liking by heating or oxidizing.
Included key ring easily attaches the whistle to a bag, belt, or keychain.
