This is a beautiful pen. Your combination is outstanding.
For the longest time I have tired this design in my pen without success. I have been slicing at a diagonal 30 degrees the pen blank about 1/4" into the blank. Then glue a strip of wood. into the slot. I have either blown the blank out. Blown the strip out. Or have not gotten the slot line even. Or the inlay wood has become so small . There has to be a balance that works.
Could you express your success into a written form.
thank you!
