What Makes The Best Ka Knitting Needles

Here are some key decision-making factors to look for when choosing the best Ka knitting needles.

What’s It Made Of?

Selected Moso and Madake bamboo grown in Japan are used. The surface is polished with natural plant wax. This gives needles excellent luster and smooth texture.

The Koshitsu line has a brown tint, and the Shirotake line is a natural color.

The Koshitsu needles have been heat and pressure treated, thus the darker color. They are then polished with plant wax.

The Shirotake needle’s surface is the natural bamboo color. The plant wax gives them a fine texture and luster.

What Type Of Needles Are They?

KA Needles offer SeeKnit Double Pointed Needles, Single pointed needles, Circular needles, and Interchangeable Knitting Needles.

How Long Are They?

Depending on the type of knitting needle, the length varies.

What Sizes Are Available?

There is a range of sizes depending on the style of the needle. The specific sizes are given below for each type.

Are They Comfortable To Use?

Kinki Amibari KA circular needles are high-quality bamboo, with an enhanced quality finish making knitting comfortable and effortless.

Do The Stitches Stay On The Needle?

There’s a fair amount of drag on the needle shaft, so they stay on.

Are They Durable?

As with any smaller diameter needles made of bamboo, they break if you don’t treat them with care.

  1. Hi I would like to know if you personalized knitting needles with the name of my company. I produce alpaca yarn and I would like to sell patterns with the needles and yarn.
