Swedish Fire Steel
Here’s a very practical gift idea. It’s a simple little key chain sized fire starter. When you slide the key looking thing against the little stick, sparks fly out at 3,000°C which is 5432°F. Yeah, that’s pretty hot.
The crazy little thing even works when it’s wet. I’m not sure anything will light when it’s when, but this thing will keep sparking. Get this for your closest friend who wants to go out and be like Bear Grylls!
