So far I am done with the bodkin. It probably isn't made in the period way, but I allowed myself some room for a creative design. Original has no associated bodkin/by-knife preserved, anyway.
At least I managed to make the bodkin handle match the dagger's in construction and style pretty closely. Compare with the dagger's handle at the above link.
Overall length 7", handle just a bit over 3.25". Handle is round in cross-section, almost exactly 0.5" diameter.
Just as dagger's, it is covered in black ray skin and has nickel silver crown shaped collars (caps, actually).
Blade is square in cross-section, tapering to point from round 0.25" diameter at the handle.
