Making a vintage marking knife

The design of this marking knife was inspired by a vintage tool.\r

I thought the way the blade is attached to the handle is much better than the ferrule we use these days, since the tool is narrower and can get easier into tight spaces.\r

To keep with the vintage look I used copper and left it unfinished so it will develop a patina in time. I also used an old piece of wood for the handle, partially rotten, cracked and full of worm holes, to go with the theme.
