How to pair cultural toys with walnuts

The pairing of cultural toys and walnuts is mainly based on five dimensions: size, shape, texture, color, and weight.

1. When matching size [SEP], it is necessary to measure the edge, belly, and height of the walnut with a caliper, and the error should be controlled within 0.5 millimeters. Different growth environments of walnuts of the same variety can lead to size differences, and it is necessary to screen for similar sizes from multiple pairs. Excessive size differences can affect the hand feel when playing, and long-term playing may result in uneven force on the hands.

2. Shape

Observe whether the pile type, shoulders, and bottom of walnuts are symmetrical. Common types include short piles, high piles, round piles, etc. When pairing, it is necessary to choose the same pile type to avoid visual dissonance caused by mixing and matching. Alien walnuts such as eagle beak and lantern require strict comparison of contour curves, and the overall fit can be observed by rotating 360 degrees.

3. Texture

Compare the distribution and depth of the main and secondary tendons on the surface of walnuts, and require that the texture direction be basically consistent. Special patterns such as lychee and ant patterns need to be matched with a high density of patterns. Excessive differences in patterns can damage the overall aesthetic appeal. It is recommended to observe the alignment of patterns from multiple angles under natural light.

4. Color

New walnuts should choose individuals with consistent leather color, while old walnuts should consider the coordination of patina color. Defects such as dark skin and yellow tips can affect color fading in the later stage, and individuals with obvious color differences should be excluded when pairing. The same fruit has the closest color, but walnuts from different years may have color differences.

5. Weight

Measure by hand or electronic scale, with a recommended weight difference of no more than 0.5 grams. The weight difference can cause the center of gravity to shift during playing, which may affect the balance of hand muscles in the long run. Walnuts with different densities may have weight differences even if they are the same size, which needs to be confirmed through actual measurement.

Walnut pairing is a systematic project, and it is recommended that beginners start with basic varieties and prioritize choosing products from the same tree or batch. During the process of playing, it is necessary to regularly clean the gaps and dirt, avoid exposure to sunlight or soaking in water, and store in a cotton bag to prevent collision. The daily playtime should not be too long, and can be assisted by a bristle brush for maintenance. It takes more than three years of continuous playtime to form an ideal patina. If color difference worsens or cracks are found, adjust the playing mode of the disc in a timely manner and re pair it if necessary.
