I was asked to share how I made the Knifes Ying and Yang. Unfortunately I do not have any photos to accompany the steps, but I will try my best to explain the process.
1/8" steel salvaged from a 12" circular saw blade
1/4" thick hardwood
1/8" brazing rod
First, I draw up a pattern ( as shown in the first photo). Normally I would transpose this pattern to a piece of Bristol board as a template including the shape of the full handle when making a full tang knife. But with these knives I wanted the blades to fit in the handle of the other. So in order to accomplish this I only made a template using the top portion of the tang (see next photo) and cut it the pattern out using a utility knife..
