The plainest piece in the range and the least forgiving. With no beading to hide behind, the taper has to be true down the whole length, because any wobble in the line shows immediately on a stem this slim.
It needs a dense wood. A softer blank turned this fine would flex in the hand and would not hold the bore true, so the blanks are picked for weight before they go on the lathe, and any that sound wrong when tapped are set aside for a thicker piece.
The oxblood is a stain worked in and then oiled to a low sheen rather than polished up, which keeps the piece looking like wood instead of lacquer. A single narrow band of brass closes the tip. That is the whole piece.
