Edo tortoiseshell fountain pen

◎ Edo tortoiseshell fountain pens It is said that real tortoiseshell feels warm to the touch. Of course, this is not because the tortoiseshell itself is warm, but because it has such high thermal conductivity that it warms up with body heat even in winter before you even notice the cold.
This is probably why tortoiseshell has been treasured since ancient times as a material for accessories worn directly on the skin, such as hairpins and glasses.
Writing instruments are also tools that come into contact with the skin.
So, I thought I'd try making a writing instrument out of tortoiseshell.
It takes the equivalent of six eyeglass frames to make this tortoiseshell fountain pen.
Rather than wrapping a single piece of tortoiseshell around the pen, this fountain pen is made by layering several pieces of tortoiseshell to create thickness, which are then hollowed out horizontally.
The proof of this is the beautiful patterns that run vertically like geological layers.
Rather than simply wrapping it flat, the craftsman's attention to detail in carving out the glossy roundness that is characteristic of tortoiseshell has resulted in the creation of this luxurious masterpiece.
The pen nib is made by the world-renowned German company Schmidt.
