InnerBark Outdoors recently released this video about feather sticks (aka fuzz sticks). It is hands down the best information that I have seen on the subject. In the video, Andy covers a refined technique for creating feather sticks safely, how to choose the right wood, and why to make them.
The ability to create quality feather sticks is one of these most single useful skills the outdoorsman can possess. It is also a test of one’s ability with a knife and the knife itself. There is a good reason you see feather sticks mentioned in nearly every survival oriented knife review.
