While perusing YouTube this morning I came across "The Art of Craftsmanship" YouTube channel and he had a wonderful method that anyone can employ with the tools as woodworkers we already have on hand.
First, you need an ol rusty file or a file that isn't usable anymore, then you need your woodworking skills and common sense.
This was an enjoyable video for me to watch anyway, not a whole lot of music, straight forward speak from the young man knife maker, and speaking in easy to understand terminology.
There are many ways to make a knife, but I thought this was one way we all, as woodworkers can wrap our heads around, and most of us already have all the tools on hand to complete a knife from a file. Hope you enjoy.
