The advantages with this type of knife:
- Gives you leverage when using rather small blades.
- No need for retouching to protect your hands. That saves on edges, which you need as you can get of in an as stone poor place as this.
- Quicker than hafting in the regular fashion.
Start the wrapping by inserting the willow branch into the crack, on the inner side of the blade. Make a few turns around on that side before taking a wrap over the backside of the blade.
Wrap the other end tightly down to clamp the blade properly. Secure the small willow branch wrap by inserting it into the crack twice.
Not exactly a work of art, but very handy. And disposable too.
