1. Each bamboo has different color
Since bamboo knitting needles are made of natural materials, the fiber, color, and texture are different for each one. Koshitsu bamboo needles that have been treated with high temperature and high pressure have different colors from light to dark brown. In addition, the color may change over the years of use.
2. Laser engraving
The size for each bamboo knitting needle is laser engraved. The bamboo has a hard lenticel part and a soft inner part. Furthermore, because the density and hardness of the fibers differ from bamboo to bamboo, there are differences in the depth of engraving.
3. Handle gently
Bamboo knitting needles are made of natural material, so if strong force is applied, the needle may break, scratches or dents may occur. If you hold the needle excessive firmly and knit it, the needle may break, such as when the stitches are tight. When handling, do not apply excessive force and handle it gently.
4. Precautions for use and storage
Since natural bamboo is used, please refrain from using it if it gets wet with water or if water vapor adheres to it. When it gets wet, the fibers on the surface of the bamboo needles become fluffy, making the needles less slippery. Also, to prevent the growth of mold, wipe it with a dry cloth after use.
Storage: Please refrain from storing in a humid place. The needle may become less slippery and get moldy.
5. What to do if the needle thread slips worse
If used for a long time, the surface of the bamboo may deteriorate and the slippage of the thread may worsen. Place the needle on a flat surface, hold the solid carnauba wax in your hand, rub the surface of the needle with the wax, and polish it with a dry cloth. The slipperiness of the thread and the gloss of the bamboo are improved.
6. How to deal with discolored metal parts
Circular needle and interchangeable circular needle have brass metal fittings and they may discolor over time. In that case, soak a cloth with a commercially available penetrating lubricant (e.ｇ. WD-40) and wipe the metal fittings. At that time, please be careful not to let the penetrating lubricant adhere to the bamboo needles. If it adheres, wipe it off immediately with a cloth.
