Let's make it during the summer vacation! Original clocks, cars, and wreaths made from koppa

Let's make an original work with the small scrap "Koppappa" that is inevitably produced in the process of making cosine!

What should I make for this summer vacation? If you are thinking, why not make an original watch, car and wreath with Cosine's "Koppa".
Koppa is a small piece of scrap that comes out in the process of making cosine. Although it is a small piece of wood, it is still a natural tree that has grown over a long period of time. It conveys the warmth and fragrance of wood and the strength of nature. Make use of the texture of wood and make your own clocks, cars, and wreaths as you imagined during this summer vacation! !!

Why does "mill ends" come out?

What is the "mill ends" that are inevitably produced during the manufacturing of wood?
In a nutshell, it is the part of wood that is not used as a product. At Cosine, we want to make the best use of wood by using as little "mill ends" as possible. For example, a material with small "knots" that are traces of tree branches becomes "mill ends" if cut off, but it becomes a product by making use of it in the invisible part. Pieces that are too small to make a large product can be used by making a smaller product. Even if you make an effort to use up all the materials without producing "mill ends" as much as possible, the parts to be cut off when the lengths of the round bars are accurately aligned and the various shapes that appear when cutting the shape of furniture. Fragments become "scraps" that are very difficult to use elsewhere.
"Koppappa" collects small pieces of wood that come out at the very end and uses them as materials for work. I would like you to use your power and imagination to make wonderful original items from the small pieces of wood that come out at the very end! It is an item filled with the feelings of cosine that was created from the thought.

"Koppappa" contains various kinds of trees used in cosine manufacturing.

As mentioned above, Koppa is a small material that comes out in the process of making cosine, so the five types of wood used in cosine products are randomly included. Maple walnut is used more often than other materials, so it's also abundant. Find out what kind of tree it contains. If you know the type of wood, you can enjoy the work even more.
Maple Origin: Quebec, Canada Classification: Aceraceae
Sap is a tree species that is used in syrup and is also known as the Canadian flag. Cosine products are made from hard maple, which grows to a height of 40m and a diameter of about 1m in the harsh and beautiful nature of North America. It is a wood that has been used for furniture in Europe and the United States for a long time, and because of its tough material, it is also used as a flooring material and as a material for elaborate musical instruments such as pianos and violins.

Walnut Origin: Midwestern North America Classification: Walnut Family
Walnut is one of the three most famous trees in the world. Speaking of walnut trees, you will feel familiar with them. Due to its heavy texture, it has been popular as a furniture material in Europe since the Renaissance era. In the archetypal era of the west, it was believed that the color of the material became darker when iron was driven in, and nails and bullets were driven in, so bullets may come out of the sawn timber. (It actually came out!)

Oak production area: All over Hokkaido Classification: Fagaceae
The magnificent tree shape and vitality have been revered as the "King of the Forest". Because it is a slow-growing hardwood, most of the furniture materials are over 150 years old. One of the characteristics of oak wood is the unique striped pattern of tigers called "tiger spots".
Materials with excellent strength and durability have long been used heavily in construction, furniture, and ship materials.

Sakura Producing area: All over Hokkaido Classification: Rosaceae
We are using "Yamazakura" from Hokkaido. The material is sticky and strong, easy to cut and has little warpage, so most of the woodblocks for printing ukiyo-e and books in the Edo period were wild cherry blossoms. Since Yamaza Sakura cannot take large materials, there is a part where the reddish and white thick parts, which are the characteristics of Sakura, are clearly separated. It is a material that you want to enjoy the beautiful colors that nature weaves.

Tamo production area: All over Hokkaido Classification: Oleaceae
Most of the tamo from Hokkaido are called Yachidamo, which is also known as tamo. It is called Pinni in Ainu language. It is a material called Ash in English. The height is 30m, and the thickness of the trunk is 1m. It grows large enough to grow to a diameter of 1m. It has a beautiful and uniform grain and has been popular as a furniture material for a long time.
