Last year i made the little brother of this guy. Went a bit "fancy" and gave it some tiger stripe intaglio etching using the gun blue and bleach method.
Just need to put on the turks head and seal the handle.
The gun blue and bleach causes rapid oxidation like an acid etch would but instead your using a base to build that rust layer on the outside of the knife. Guys like Chuck Burrows uses it on his frontier style blades but i don't think he soaks as long as i do. I used a pure bleach solution for 3 hours to build an intaglio effect.
