Outdoor Element Fire Flute™ – Everyday Carry Aluminum Emergency Signal Whistle & Fire-Starting Ferro Rod with Water-Tight Tinder Storage | Survival Gear for Camping, Hiking, Bug-Out Bag & 72 Hour Kits

It functions more or less the same as any other Ferro rod I've used. You got a somewhat short but pretty thick fire steel so you're going to get quite a few strikes out of it. The tinder is also pretty good but you'd want to use it in conjunction with other materials to create a tinder bundle as the tinder on its own simply isn't going to be enough. The only "issue" is that the whistle on the top isn't terribly loud so if you were going to take this with you on a hike, camping trip, or throw it in your go bag you'd want to have another dedicated whistle to supplement this one. Overall, decent little thing.

This is heavier than expected but usefulIn an emergency situation
