BJ CLASSIC COLLECTION

In order to shine a light on vintage frames that have been weeded out over time, BJ Classic is based on actual vintage frames and has been revived using modern cutting-edge technology with thorough attention to detail. Collection”.
We have a collection of frames with classic designs that are now attracting attention again, and each time you wear them, you can feel the story and depth of the frames. It's classic, but for some reason there are a lot of new frames. If you want to get the vintage style that is currently attracting attention at a reasonable price, this is the brand you should choose without hesitation.

WORK FLOW

In addition to the celluloid frame like the "P-501", BJ's commitment is also packed in.
Here, we will introduce you to the detailed points that only experts could know until now.

point 1 “Caulking pin”

Just like the front decoration, each of the crimping pins, which are a symbol of BJ, are handmade one by one.
After cutting a thin metal plate into a very small round shape with a diameter of 3 mm, we solder it to the pin part, and then cut it out into a star shape. Furthermore, the gala event will be held four times. After cutting the die, apply rough and glossy coatings, wax it, cut it into a star shape, and polish it four times in total to make the hexagram shine.

pint 2 [minus screw]

Considering production efficiency alone, I would like to use Phillips screws because they are easy to tighten, but BJ always sticks to flat head screws.
This is because they are simpler than Phillips screws, and have a sophisticated and beautiful design with no waste. A flathead screw made by cutting can be tightened until it becomes flat against the tip. This makes Neji and Tomo look as if they are one integral part, making BJ even more beautiful. Currently, flat head screws, which are made by cutting rather than forging, account for only about 10% of the industry total due to production cost constraints.
This kind of attention to detail creates a product that can be called perfect.

point 3 [Butterfly nose pad]

The free-position, swaying nose pads that you often see tend to shift from the nose and cannot be fixed in place.
BJ's butterfly nose pads are designed to be fitted, and will fit perfectly on the nose of the person wearing them. Now, pure titanium has also been added to the lineup, giving it an even more luxurious feel.

point 4 [Titanium Temple - NT]

BJ's titanium temples are made from pure titanium round wire with a diameter of 5mm to 6mm using a method called swaging.
Swaging is a technique of tapping and stretching round wire, which can increase metal density, improve springiness, flexibility, stiffness, and strength. The spring, top, and modern parts of the stretched metal are flattened and trimmed by swaging, and then pressed several times to further improve the springiness and other features. It has the effect of maintaining a feeling of hold after the fitting.

point 5 [reverse wisdom]

BJ also reduces daily stress.
In the case of Satoshi, where the lens and temple are held together by one part, tension is applied to the screw when the temple is opened, so one of the temple screws tends to loosen. BJ uses the traditional method of attaching screws with the left and right sides reversed to make them more difficult to loosen.

point 6 [Hinge]

Depending on the size of the temple, use 3-blade, 5-blade, or 7-blade hinges.
Generally, even large types often use 3-piece hinges, but BJ also uses 7-piece hinges, which are difficult to embed, to increase strength. Also, the reason why it opens and closes smoothly is because it uses highly technical domestic hinges.
We pursue the essence of the product without seeking cost reduction or efficiency.

Masterpiece model of BJ CLASSIC COLLECTION

All processes of making P-501

Born in the early 2000s
BJ CLASSIC COLLECTION.
Among them, the P-501, which became a representative model, was created after a production period of about 4 months.
It has a soul as eyewear.
Follow the entire process of BJ being born from a piece of celluloid.

point 1 [Cutting celluloid fabric]

BJ is particular about celluloid frames.
Its shape retention, luster, and fit give it a quality feel that is incomparable to the currently mainstream acetate fabric.
On the other hand, there is a risk of ignition at 170 degrees, so it cannot be mechanized and can only be handled by skilled craftsmen.
In addition, BJ's thickness varies depending on various conditions such as color, even if the model is the same.
The craftsman determines the thickness using his eyes and hands.

point 2 [Rounding of celluloid fabric]

Create a gentle curve on the cut celluloid fabric.
The dough is placed in special oil that is heated to a high temperature, pressurized, and instantly cooled.
The timing of all tasks depends on the sense that the craftsman has cultivated over many years.

point 3 [Glass-shaped die cutting]

This process cannot be fully mechanized due to the risk of fire.
The manual work of craftsmen continues.
The rounded celluloid fabric is carefully cut out one by one to create a ball shape.
Then dig a V-groove for the lens.

poinr 5 [Cutting the outer frame]

Next, cut out the outline.
The form of P-501 emerges from a single sheet of celluloid fabric.

point 5 [Nose pad attachment]

In BJ, it is impossible for all nose pads to be in the same position.
This is because the best position for wearing comfort differs depending on the model.
The nose pad prototype, which has been carved out to a large size, is first pasted on and then rested for a few days.
After the pieces are completely adhered to each other, craftsmen manually carve them to fit the shape of each model.
The series of work involved in this nose pad is the deciding factor in the comfort of BJ's first impression.

point 6 [rough cutting]

Highlights of BJ's celluloid frame making.
A craftsman files each piece of the front frame carved out by the blade.
A craftsman's experience, intuition, and passion create nuances that cannot be expressed by machines, such as gentle curves and sharp edges.
This is the moment when BJ's shape and texture are born.
Like the front frame, the temples are also rough-hewn by hand.
It's no exaggeration to say that there are almost no brands other than BJ that have rough edges on their temples these days.
This invisible effort creates a smooth ear and texture.

point 7 [Aragara case]

Abrasives and polishing chips are placed in a rotating drum called a gala, and the carved front frame and temples are placed separately.
The composition of Gala is a secret and is kept secret. The composition changes depending on the temperature and humidity of the season.

poimt 8 [Mud buffing]

Carefully polish the parts that have been turned around. Dissolve the powdered abrasive in water and knead it.
By polishing with fine-grained, high-quality mud, the luster dormant inside the celluloid is brought out even more.

point 9 [Intermediate glass / glossy glass case]

The parts polished with mud buffing are put into an intermediate glass with a different composition, and then into a glossy glass. This is a total of 3 times.
Normally, a gala event is completed in 4 to 5 days, but at BJ, the drums are played for over a week. To be exact, it will take a total of two weeks, one week at the front desk and one week at the temple.

point 10 [Hinge crimping]

In order to match the frame hinge and temple hinge, embed a caulking pin in the temple. Align the hinge and pin together with the core metal inside the temple.
The star on the caulking pin is not only for its design, but also for the purpose of firmly fixing the hinge by making the protrusions of the star bite into the fabric.

point 11 [Hinge embedded]

The hinges are embedded into the frame using a embedding machine that is heated by passing an electric current through it.
Again, the key point here is the temperature of 170 degrees. We will carefully monitor the timing and proceed with the work.

point 12 [mud polishing]

Polish the mud to adjust the joint between the front and temples.

point 13 [Gloss polishing]

Once the mud-polished frame is finished, the front and temples are separated and each part is buffed and polished. After that, the frame is reassembled and polished.
The reason why BJ is called BJ may be due to this uncompromising polishing process. The celluloid material shines even more, and a beautiful light appears.

point 14 [Front decorative stud attachment]

BJ's symbol, the wings of a bald eagle, are embedded in the highly polished celluloid frame, which embodies the brand.

point 15 [engraved]

If you don't go through all the steps up to this point, you won't be able to carve your name into it. Only those with a finish that can be proud of as a BJ are engraved.

point 16 [Inspection]

The examination continues even after stamping. The craftsman himself carefully checks the overall balance and fine details.
BJ's mission is to deliver products as well as perfection.
This is how a presence that will remain even 100 years from now is created.
