by hand work of Sabae craftsmen
The skill and the spirit of Sabae eyewear craftsmen with history of over 100 years.
Every eyewear that has essence of manufacturing by hand work of Sabae craftsmen is

SHINBARI
芯張り
The metal core installed in the ear hook bar of eyewear, called the temple, serves not only for fitting, but also beautiful and delicate patterns were engraved on it in the past, and many of them were highly designed.
The engraved pattern delineated by advanced craft skill clearly emerged, enhancing the value of eyewear.
ShinbariCraftsmen called the temple crafting method that mainly features the metal core, that is sandwiched inside.
However, Shinbari that requires labor, time, and high skill, declined gradually, with the change to the generation that demands the productivity, and the number of skilled craftsmen decreased drastically.
Currently, there is the only one craftsman in Sabae, who continues to inherit Shinbari, that is disappearing from the world.
Life was beautifully and dynamically brought to Shinbari series by this craftman.
WORKFLOW
Hole engraving on plastic sheet
Creating foundation for sandwiching metal core
in plastic sheet
The groove hole is engraved on one side of the strip shaped plastic bar, matching the shape of metal core to set in. The plastic and the metal core are located precisely to fit each other.
Metal core embedding
Installing metal core
on engraved hole and semi lamination
The metal core is installed on the hole side of the plastic bar, upon melting the surface slightly by solvent. Then clear plastic is layered on top, and the entire plastic bar is temporarily fastened with a clip.
Metal engraving
Metal engraving core inspired by American vintage design
Engraving pattern design on the temple core combines the straight lines and the smart curves to give a geometric image. The luster of plastic and the sharp texture of metal combine delicately to enhance high quality vintage feel.
Molding
Setting temporarily
fastened plastic bar with core in dedicated mold
Visual check is done for piece by piece if solvent has infiltrated, neither peeled nor floated, and additional solvent is poured if necessary. Afterwards, the plastic bar is set in the dedicated mold for heat treatment.
Steel plate to prevent sticking
Inserting steel plate in between to prevent plastic bars
from sticking each other
The steel plate is inserted between the plastic bars to avoid sticking each other caused by heat treatment. Longtime experience and knowledge lead him to execute this extra effort.
Heat treatment and cooling
Heating plastic bar set
in dedicated mold, and cooling it
The metal core is embedded firmly into the plastic by repeated heat treatment and cooling. It is one of the most delicate and high skills that craftsman makes sure the metal core is not bent irregularly by pressing process. Since the condition of plastic material varies depending on color and production lot, craftsman maximizes his sense and intuition to adjust time, temperature and pressure.
Taking out of mold
Taking plastic bar out of mold
The lid of the mold is removed by the dedicated tool. Then the pressed plastic bar is taken out to be inspected carefully for every single detail, checking if there is no separation of the plastic, as well as the adhesion failure.
Sight check
Checking by sight if there is not bubble melded
Another careful inspection is done for piece by piece in detail to check if bubble that occasionally gushed during heat treatment and could not be removed properly.
Separation
Removing steel plate
The steel plates, set between plastic bars, are removed one by one, Craftsman uses the dedicated tool that he made only for this process.
Carving
Forming temple shape by carving plastic bar
The strip shaped plastic bar is machined into the temple shape to make it comfortable on ears. There are limited numbers of craftsmen who can handle this old school machine that is rarely used, while productivity is required in these days.
Finish
Polishing temple to
make it shine, and finishing by caulking pins
to install hinge
Once the temple shape is formed, it is set in tumbling barrel, called “Gara”, and polished to make the surface glossy. Afterwards, the finish is completed by calking pins of hinges. Finished temple with gorgeous engraving patterns projected makes the whole frame exist beautifully constructed work.
