MANUFACTURING METHOD

Full bonding

This technique is said to be the most luxurious for leather products, and carries all the benefits. Combining two sheets of leather with different fiber directions brings about extreme robustness. Therefore, it becomes possible to make a very thin product.
Such product also has flexibility like a thinly sliced rubber plate.

We use the full-bonding technique for almost all the products, either totally or partially, as required.

Polishing of edge

We use a technique called "cut edge" for almost all the products.
Cut edge means a sharp edge that leather has just after being cut.
A leather product needs to have such a sharp edge processed by another technique called "polishing".
As the name suggests, polishing uses a cloth to polish sharp edges, making them smooth.

Almost all the leather products in the world have a different finish. They apply paint to edges to finish.
On the contrary, we use a traditional technique: dye the edges and then polish them with a cloth to finish.
Because this traditional technique requires a lot of labor, it is rarely performed around the world.

Let us add one more thing. Currently, you often hear the words "Hon Migaki" (true polishing) instead of "Migaki" (polishing) . There is no such thing like true polishing, but it was devised because painting edges as described above began to be called "polishing" by mistake. So we guess people wanted to distinguish genuine polishing from 'polishing'.

Post-cutting of edge

In addition to cut edge, there is another technique to treat an edge called bagged edge in which the surface leather is turned inside. We use cut edge for almost all the products but for inner treatment, we use the bagged edge technique for almost all the cases. In this technique, after bagging an edge, the margin of the edge should be cut along the closest possible line to the stitching to make the edge look as thin as possible.

This technique was originally developed in ancient Europe and it didn't exist in Japan.
A painting even by a greatest master will be of little value if only the canvas is hung on the wall. As merchandise, it will not attract people unless it is decorated in a fine frame. We noted this idea of a frame and adopt the technique of edge cutting.
