Each of a set of knitting needles have a length correlated to at least two factors (e.g., needle diameter, and yarn weight) to provide appropriate strength, stability, and suitable take-up for stitches created during the knitting process. The correlation is such that as needle diameters (D) grow, and/or the yarn weight increases, the needle length grows in a particular relation, as follows: $L=\frac{\left(W+2\right)\left(15D+15\right)}{\left(\mathrm{.4}W+2\right)\left(\mathrm{.9}D+5\right)}$
where “L” is the length of the needle, “D” is the needle diameter, and “W” is the yarn weight from 0 to 7 (i.e., lace=0, super fine=1, fine=2, light=3, medium=4, bulky=5, super bulky=6, and jumbo=7). Raw wood for the needle is stabilized in a process including application of a composition that is maintained thereon for a period of time and in a vacuum, and heat treatment.

Example knitting needle connector assemblies, e.g., for a knitting needle or crochet tool, may include first and second members. The first member may be generally cylindrical and have a radially facing slot extending circumferentially about a longitudinal axis of the first member. The second member may have one or more radially projecting pins received in the slot, wherein the one or more pins are movable about the circumferentially extending slot such that the first member is rotatable with respect to the second member about the longitudinal axis.

A bendable straight knitting needle consisting of at least three parts that provides ergonomic benefit by enabling bending of the needle during stitch/loop creation by the knitter typically done with two knitting needles, one in each hand. The addition of the bendable portion to the standard conventional straight knitting needle would allow flexible knitting motion with enhanced comfort and better ease of knitting in a tight place.

A tool designed for fixing fibers, such as natural hair, to a substrate, such as a wig cap, for making hand-tied wigs, having a shaft with two ends. A slot extends from one of the shaft ends with an open end to receive fibers. An opening extends transversely to the shaft and intersects with the slot for holding fibers as they are passed through the openings of the wig cap.

A crochet anti-slip structure includes a crochet shaft and an anti-slip sleeve. The crochet shaft is rod-shaped and has a crochet section and a binding section, and at least one arc-shaped convex body having an expanded diameter is disposed at the outer periphery of the binding section. The anti-slip sleeve is made of elastic plastic and has a binding hole configured to be opposite to the binding section for inserting the binding section into the binding hole to achieve an anti-slip effect between the crochet shaft and the anti-slip sleeve as well as an anti-slip effect for a user to grip and use a crochet.

A connection structure includes a proximal end of a needle body, a metallic connector fixed to the proximal end, and an end of a flexible cable attached to the connector. The connector includes a shaft and a head diametrically greater than the shaft. The proximal end of the needle body has a hole into which the shaft of the connector is fitted. The head of the connector has a cable recess accommodating the end of the cable. The cable recess includes a first recess adjacent to an opening of the cable recess and a second recess adjacent to and diametrically greater than the first recess. The end of the cable includes a first portion accommodated in the first recess and a second portion connected to the first portion and accommodated in the second recess. The second portion is diametrically greater than the first portion.
