Seeknit Koshitsu Bamboo Asymmetrical Circular Needles (Fixed)

Japanese precision. Hardened bamboo. Ergonomics designed around your hands.

Seeknit Koshitsu Asymmetrical fixed circular needles combine refined Japanese material technology with a deliberately asymmetrical needle design. These needles are created to support the natural mechanics of knitting, offering greater control, reduced hand fatigue, and a noticeably smoother working rhythm.

All needles in this series are made exclusively from Koshitsu-treated bamboo, Seeknit’s premium hardened bamboo, developed to deliver superior durability, stability, and precision while maintaining the warmth and lightness bamboo is valued for.

Japanese craftsmanship and functional design
Manufactured in Japan by Kinki Amibari Co., Seeknit needles reflect over a century of specialized bamboo expertise. The asymmetrical construction is intentional and functional, based on careful observation of how knitters actually work, rather than on visual design alone.

Asymmetrical tips for balanced knitting
Each needle pair features two tips of different lengths:

• the longer tip provides stability and precise stitch pickup;

• the shorter tip allows stitches to move off the needle smoothly and effortlessly.

This configuration mirrors the natural role of each hand during knitting, improving efficiency and reducing unnecessary movement. The result is a more fluid, controlled knitting experience, especially noticeable during extended sessions or fine, detailed work.

Koshitsu-treated bamboo performance
The bamboo used in these needles undergoes a specialized heat and pressure treatment that densifies the material. This process:

• increases hardness and resistance to wear;

• improves dimensional stability over time;

• creates a smoother, more refined surface;

• enhances stitch control, particularly on smaller needle sizes.

Compared to standard bamboo, Koshitsu bamboo feels more precise and composed, offering confidence without stiffness.

Refined tips and seamless joints
The needle tips are shaped for accuracy without sharpness, allowing clean stitch pickup without splitting yarn. The transition between bamboo and the metal connector is perfectly smooth, ensuring uninterrupted stitch flow and eliminating snagging.

Rotating, memory-free cables
Seeknit’s transparent cables feature a rotating swivel joint that prevents twisting during use. The cables are soft, flexible, and completely free of memory, allowing them to follow hand movement naturally without drag or resistance, even when knitting small circumferences.

Sizes and lengths
Seeknit Koshitsu asymmetrical fixed circular needles are available in a carefully curated range of needle sizes suitable for fine to medium-weight projects. The short circular length is ideal for small circumference knitting such as socks, sleeves, mittens, cuffs, and baby items, while still offering control and comfort.

Sustainability through longevity
Bamboo is a fast-growing, renewable resource. The Koshitsu treatment significantly extends the lifespan of the needles, reducing replacement frequency and supporting a more sustainable approach to premium tool making.

Who these needles are for
These needles are designed for knitters who value ergonomic refinement, knit for long periods, work with fine yarns, and appreciate tools that quietly improve performance without visual excess.

Seeknit Koshitsu asymmetrical fixed circular needles are not simply bamboo needles. They are purpose-built instruments, engineered to support how you knit — precise, balanced, and unmistakably Japanese.
