Make your own version of the northern nomad's woodworking tool.
The crooked knife is the northern nomad’s woodworking tool. All the northern tribes in North America and Asia have their own version of it. My farm relatives use them to trim their horse’s hooves. I think that whatever wave of invaders brought horse culture to Europe must have brought this style of knife with them.
I made this particular knife years ago from plans in the book Wildwood Wisdom by Ellsworth Jaeger (1945).
