Making handles" that determine the impression of a bag with handles

 持ち手付き鞄の印象を決める「ハンドルづくり」

Introduction.

Pride and skill spun by a 70-year career

Mr. Tanejiro Ishii has had a long career as a bag craftsman for more than 70 years. He is still active on the front lines as a craftsman at Yoshida K aban, one of Japan's leading bag manufacturers. As a "master bag craftsman" who preserves his meticulous handiwork to the present day, he has been working on a series of stately business bags made of genuine leather under the PORTER brand.

In 2018, PORTER was awarded the "Japan Leather Goods Meister" by the Japan Leather Industry Association in the bag category. The "PORTER CREDO" series, which is only available at limited stores, won the GOOD DESIGN award in 2017.

We visited his workshop in Adachi-ku, Tokyo, where he has lived unchanged for the past 67 years since becoming independent, to hear about his craftsmanship and his thoughts on manufacturing. In the latter half of the interview, we will show you how to make "handles," the most important part of a bag with handles.

Making handles" that determine the impression of a bag with handles

Work that can be done even if it rains

I understand that your career spans more than 70 years. What led you to leather craft?

It was a time when the scars of the postwar period were still fresh in my mind, before the rapid economic growth of Japan. I was 16 years old at the time, and on the advice of my parents, I was encouraged to become an apprentice to my uncle, who ran a bag shop. I remember well that I was told to get a job that I could do even if it rained, as supplies were scarce due to the reconstruction efforts. I guess they were grateful just to be able to work under a roof. In those days, I earned about 300 yen a month as a live-in worker, but it was enough to have fun. When I got a day or two off each month, I would go to Asakusa with my money in my pocket. I enjoyed going to Asakusa for one or two days off every month, going to the cinema, seeing a play at a place called "Tokiwa-za," and eating delicious curry udon noodles on the way back home. After that, I became independent and have been making bags in this workshop ever since.

 

The fun of creating from scratch

The number of hands-on jobs is decreasing. What do you find attractive and interesting about your job, Mr. Ishii?

For example, even if we purchase cowhide, there are seasonal differences between "spring cowhide" and "fall cowhide," and no two pieces are the same. It is a difficult and interesting process because we have to take the same parts from different shapes and textures, and make them according to the design. There is a unique feeling when you are working with good leather. It is interesting to create a bag from a single large piece of leather in this way. The other thing is that your work is seen by others. Craftsmen have a competitive streak, and I don't think they improve unless they are aware that others are watching them. I was delighted when Kichizo Yoshida, the founder of Yoshida Bakan, told me about his reputation in the past, saying, "A customer from England praised my work, saying, 'There are no craftsmen like this in England. In this way, I think only about my work whether I sleep or wake up, but even so, I am not often satisfied. Maybe it is because I am not satisfied that I have been able to continue for 70 years.

A 70-year relationship with Yoshida Kaban

What do you value and keep in mind as a craftsman in your "tripartite manufacturing" with Yoshida Kaban?

We make sure to check the designer's intentions and create the product faithfully. It would be too cramped if we had to design for our own convenience. Designers are free to design with a variety of feelings in mind. Our job is to take those drawings and turn them into samples from paper patterns. For example, we think about where to use the best leather to make the necessary number of parts from a single piece of leather. For example, for the handles we are going to use in this project, we have to use the part of the leather with the best expression to make it look good. The skill of the craftsman is to make it beautifully and without waste. My uncle, who is also a master craftsman, had a good relationship with Yoshida Kaban from that time. I took over the business, so we have been together for more than 70 years now. My master also skillfully uses difficult parts of the body and utilizes them in the right places where they would normally not be used. I learned to work by thinking and applying these techniques on my own. In any case, I tried to watch my master's work closely.

Sex and elegance are not numbers.

Did you have any difficulties from your training period until now? What were some of the difficulties and how did you overcome them?

Leather from a single cow has different softness and firmness depending on the part of the cow, so we are always thinking, "Well, what kind of leather do we have today? I always face the leather thinking, "Well, what kind of leather do I have today? It is not easy to determine the condition of the leather, so I am always willing to take on new challenges. If I always do the same work over and over again, I get bored, and if I get bored, my skill will also become dull. The "kawaki" process, which is used to adjust the thickness of the leather, is particularly difficult. The thickness and hardness of the leather varies depending on the location, so if the leather is too thick, it will be too tough, and if it is too thin, it will be too slender. The handle in particular requires a lot of attention. If the leather is hard, it is better to make it a little thinner to give it more firmness, and if it is soft, you have to make it thicker to make it feel comfortable. You have to develop a good intuition for this. Even if you strain to the thickness instructed by the calipers, you will not get the same color and texture. However, if you prepare the materials properly and carefully make the bag after having the arrangements in mind, you can make a bag with a good expression. In that sense, I think it is as difficult now as it was then. But strangely enough, the bags that were more difficult to make seem to sell better.

Work should be clean and fast.

Do you have any advice for people who make things, whether as a hobby or for work?

You have to be curious and inquisitive about everything and never get tired of doing it. Nowadays, we can do all kinds of work on a computer, but it is still a good idea to be particular about the tools you use. Even with pens, notebooks, and bags, I feel that people who use them with love and care do a good job. I am not a "konya no shirobakama" (a man who wears a white hakama in a konya shop), but I don't have many bags of my own. Even so, I always sharpen my knives for cutting leather to keep them sharp. What impressed me about my master's work was that his knives were always straight. He must have been very good at sharpening and using his knives. It is not easy to sharpen a knife, because even now I tend to sharpen my knives at an angle. Also, I think it is better to look at the speed rather than the cleanliness of the finished product as an indicator of progress. Just because you do it slowly doesn't mean you can do it beautifully. There is a rhythm, or a certain amount of speed, in the work. So even if you are making something as a hobby, if you want to make it better, you should try to set a deadline as if it were work, and try to make it beautiful and fast. I think you will always come to value the set-up and preparation necessary for that.

Recipe for this issue

Why are we sharing this recipe with you?

I am good at making bags with handles, so other craftsmen often ask me how to make handles. Since it is the part of the bag that is touched the most, and it greatly affects not only durability but also usability, craftsmen are very sensitive to it. I hope to introduce the process of making handles in this issue, as it may be a part that is not often taught.

Recipes

Making handles" that determine the impression of a bag with handlesの作り方


STEP.1

Leather to fit the pattern.decisionI will do so.

<Guru's Point Advice>
When "cutting by hand" using a leather knife, cutting with the blade facing outward toward the pattern paper makes it easier to cleanly shave and trim the leather because the mountains are centered when the leather is pasted together.

STEP.2

Strain the base leathers for the top and bottom leathers and the bottom leather to a thickness of 1.0 mm using a "leather strainer". Or, you can buy 1.0mm-thick leather and prepare it.

STEP.3

Two pieces of core for the upper leather are pasted together to make a "raised core" for the top and bottom.

STEP.4

Use a knife to shave off the corners at both ends of the core for the lower leather and the core for the upper leather made in STEP.3 at an angle.

<Guru's Point Advice>
Use a leather knife to shave off the corners, but if you use a glass plate for the base, it will glide smoothly when you cut them off. The key point is to shave off the corners evenly on both sides, and not to try to do it all at once as if you were adjusting the corners.

STEP.5

The "core for raising" shaved in STEP.4 is "chamfered" with a bean canner.

<Guru's Point Advice>
The image is to apply the canner not at a right angle to the part, but at a slight angle and then pull. The blade should be used to shave off fine details for a clean finish.

STEP.6

Roughen with a file the area to be coated with rubber glue on the base leather for the main mold leather and the lower leather.

<Guru's Point Advice>
By not roughing up the area where the can is to be threaded, it will look better. Or, if you want to make it stronger, you may rough it up and then apply cosmetic leather.

STEP.7

Attach the raised core to the base leather for the main type leather and the lower leather, respectively. Use a roller to firmly adhere them to each other.

STEP.8

The upper and lower dressing leathers are pasted together using "ipponen" to firmly form the upper and lower dressing leathers.

<Guru's Point Advice>
If you imagine the handle when pasting it in and make a folding habit, you will end up with a clean and smooth handle.

STEP.9

Cut off the overhang with a leather knife.

<Guru's Point Advice>
Instead of cutting off the pieces all at once, proceed slowly and carefully while checking the cut areas.

STEP.10

With a leather knife, strain the two ends of the upper leather at an angle to each other so that they fit together perfectly.

Watch the video of the thrust

<Guru's Point Advice>
The only way to determine the angle is to rely on intuition, but the trick is to lengthen the area of the overlapping parts to increase strength. If the overlapped area feels bumpy or uncomfortable to the touch, carefully shave it with a knife to fine-tune it.

STEP.11

Only the edge of the part where the hook goes through is finished first, so that only that part is finished.filing (e.g. a file)I will do so.

STEP.12

Apply dye to the area filed in STEP.11, polish with CMC (solvent to treat the koba), and varnish.

<Guru's Point Advice>
File prepared areas, such as the edge, can be polished with a rounded piece of glass plate to create a smooth and tight look. Also, mixing glossy and matte varnishes in the desired mixture makes it easier to create the desired look.

STEP.13

Paste firmly through the cans.

<Guru's Point Advice>
When pasting, it is best to start from the butt joint first to ensure a clean paste. If rubber glue is applied too thickly, it will stick out from the cross section, so the trick is to apply it as thinly as possible.

STEP.14

In preparation for the eyelet and drilling, the area where the "base leather" is attached to the upper and lower leather is roughened with a file.

STEP.15

First, "Meuchi" is hammered into the upper leather, and "Hishikiri" is used to penetrate it.

<Guru's Point Advice>
The key is to aim at the edge of the core of the upper leather and firmly strike the edge of the upper leather, and strike the ends across the lower leather to increase strength.

STEP.16

Paste the upper and lower leather together.

STEP.17

Penetrate the hole made in STEP.15 to the lower leather with a "rhombus drill".

STEP.18

Stitch firmly with "flat stitches" while using equal force on both sides with the "Uma".

<Guru's Point Advice>
The first and last stitch is sewn back three times to create a strong handle.

STEP.19

In order to eliminate biting when holding it, the edge is chamfered with a "bean canner" and then filed.

Watch a video of the cannering process

STEP.20

Apply dye, polish with CMC, and varnish to clean up the koba surface and other surfaces.

<Guru's Point Advice>
When fibers such as the edge of the handle turn up, roller-tighten them frequently to create an interesting handle. Although the feel of the handle is invisible to the eye when touched by hand, this one small step makes a bag with a certain elegance.

STEP.21

Finish polishing and you are done.
