In the last few years, we have been monitoring discussions on the <a href=\"https:\/\/www.reddit.com\/r\/chopsticks\/\">r\/chopsticks<\/a> subreddit. A few common issues surface from time to time. Some of these are in fact already addressed by our existing articles in the <a href=\"https:\/\/marcosticks.org\/topics\/timeless\/physics-of-chopsticks\/\">Physics of Chopsticks<\/a> category. But new and unanswered questions have also been asked. The &#8220;Why Can&#8217;t I Chopstick&#8221; series will answer these new questions.<\/p>\n\n\n\n<p>One common problem mentioned by learners of <a href=\"https:\/\/marcosticks.org\/the-standard-grip\/\">Standard Grip<\/a> has to do with tips of chopsticks. Specifically, a practitioner is unable to make tips of the two chopsticks come together. He or she can extend chopsticks apart from each other. But when bringing them together to pinch food, they are unable to make chopstick tips meet. Instead, tips swing past each other by a wide margin, as following videos show.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:40%\">\n<figure class=\"wp-block-video\"><video height=\"720\" style=\"aspect-ratio: 720 \/ 720;\" width=\"720\" controls loop muted poster=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Why-cant-I-chopstick-Chopstick-tips-wont-pinch-Seq-for-blog-u_iiRaz0r-Side-2-video_s1_FRD-video-block-poster-img.jpg\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Why-cant-I-chopstick-Chopstick-tips-wont-pinch-Seq-for-blog-u_iiRaz0r-Side-2-video_s1_FRD.mp4\"><\/video><figcaption>Chopstick tips won&#8217;t pinch together<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:40%\">\n<figure class=\"wp-block-video\"><video height=\"720\" style=\"aspect-ratio: 720 \/ 720;\" width=\"720\" controls loop muted poster=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Why-cant-I-chopstick-Chopstick-tips-wont-pinch-Seq-for-blog-u_iiRaz0r-Top-1-video_t1_FRD-video-block-poster-img.jpg\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Why-cant-I-chopstick-Chopstick-tips-wont-pinch-Seq-for-blog-u_iiRaz0r-Top-1-video_t1_FRD.mp4\"><\/video><figcaption>Chopstick tips won&#8217;t pinch together<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><\/div>\n<\/div>\n\n\n\n<p>This article is brought to you, courtesy of u\/iiRaz0r from Reddit.

But not all of these required skills can be mastered quickly nor at the same time. In fact, a sizable population cannot actually wield the <a href=\"https:\/\/marcosticks.org\/caswellian-thumb-and-chopsticks\/\">Caswellian thumb pose<\/a> required by Standard Grip, due to anatomical reasons, as we discussed in the Caswellian article, and in <a href=\"https:\/\/marcosticks.org\/the-art-and-science-of-chopsticking\/\">The Art and Science of Chopsticking<\/a>. For most adult learners, even after you understand Standard Grip intellectually, it mail still take time for you to build up muscle strength, in order to wield Standard Grip properly and efficiently.<\/p>\n\n\n\n<p>As the earlier quote clarifies, each unhappy Standard Grip is unhappy in its own way. A proper Standard Grip moves chopsticks in such a way that their tips meet at the closed posture. If you can&#8217;t make tips pinch together, then you are wielding an unhappy Standard Grip, in your own unhappy ways. Assuming that you don&#8217;t have anatomical constraints, this article will discuss various common causes that prevent you from making tips of chopsticks meet.<\/p>\n\n\n\n<p>We&#8217;ll start by comparing one particular unhappy grip shown below left, to the happy one shown below right. Both pictures show practitioners extending chopsticks apart, at the open posture. What differences do you see, between the two pictures?<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"259\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-open-posture-u_iiRaz0r-Side-2-video_s1_FRD-1024x259.jpg\" alt=\"\" class=\"wp-image-10108\" srcset=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-open-posture-u_iiRaz0r-Side-2-video_s1_FRD-1024x259.jpg 1024w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-open-posture-u_iiRaz0r-Side-2-video_s1_FRD-300x76.jpg 300w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-open-posture-u_iiRaz0r-Side-2-video_s1_FRD-768x194.jpg 768w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-open-posture-u_iiRaz0r-Side-2-video_s1_FRD.jpg 1327w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>Unhappy grip (left) vs happy grip (right) at the open posture<\/figcaption><\/figure>\n\n\n\n<p>In both pictures above, practitioners hold chopsticks mid-stick. This is not what we usually recommend. We usually recommend holding chopsticks aft-stick. But as discussed in <a href=\"https:\/\/marcosticks.org\/under-swing-n-crossedness\/\">Out with the Crossed Type, in with the Under Swing<\/a>, finger placement along the length of chopsticks is not a problem that needs fixing, but rather a personal preference. In this article, we show Standard Grip being held mid-stick, for the sake of matching the unhappy ones in appearance, for easier visual comparison.<\/p>\n\n\n\n<p>Here we have the unhappy grip compared to the happy one, at the closed posture.

It allows an entire finger to exert forces on the stick, not just at one Archimedean \u201ceffort point\u201d, but on a large area of chopstick surface. There is not a single fulcrum. But instead, an entire finger surface from another finger serves as counter force to securely cage and sandwich the chopstick, turning it into a cantilever extension of fingers.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1.png\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"618\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1.png\" alt=\"Top stick as extension of tripod hold - compression vs extension tests\" class=\"wp-image-3914\" srcset=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1.png 2048w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1-300x91.png 300w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1-1024x309.png 1024w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1-768x232.png 768w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Top-stick-as-extension-of-tripod-hold-compression-vs-extension-tests-scaled-1-1536x464.png 1536w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/a><figcaption>Top chopstick as a cantilever extension of tripod-hold fingers &#8211; compression vs extension tests<\/figcaption><\/figure>\n\n\n\n<p>We&#8217;ll have more to say about this planetary gears principle and the twirling motion later. For now, we just want to highlight how an unhappy Standard Grip often does not evidence a strong cantilever extension.

This is an indication that your unhappy grip suffers from a second issue, which we will discuss next.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Lack_of_air-quote_twirling\"><\/span>Lack of air-quote twirling<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>As discussed in details in <a href=\"https:\/\/marcosticks.org\/how-to-use-chopsticks\/\">Learn to Use Chopsticks<\/a>, the only way for the top chopstick to move with an expansive range is for fingers to roll it with an air-quote gesture. The GIF below left shows an exercise you can undertake, in order to appreciate how this motion works. Note how edges of the chopstick confirm that the top chopstick has been rolled for about 180\u00b0. Then practice an exaggerated version of Standard Grip as shown below right. Focus first on the open posture, and on orienting the top chopstick for a total incagement by the index finger and the middle finger. Make sure that your thumb pad meshes with the surface of the chopstick, and rolls the chopstick along, as index and middle fingers bring the chopstick down in an air quote gesture.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:40%\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2019\/12\/Twirling_step1_practice_rolling_top_chopstick_like_a_pen_IMG_3624.gif\"><img loading=\"lazy\" decoding=\"async\" width=\"478\" height=\"400\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2019\/12\/Twirling_step1_practice_rolling_top_chopstick_like_a_pen_IMG_3624.gif\" alt=\"Chopsticks Marcosticks - Twirling step1 practice rolling top chopstick like a pen IMG_3624\" class=\"wp-image-917\"\/><\/a><figcaption>Practice rolling top chopstick<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2019\/12\/Twirling-top-chopstick-Snapping-air-with-max-wide-open-angle-Bottom-chopstick-anchored-IMG_3620.gif\"><img loading=\"lazy\" decoding=\"async\" width=\"910\" height=\"456\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2019\/12\/Twirling-top-chopstick-Snapping-air-with-max-wide-open-angle-Bottom-chopstick-anchored-IMG_3620.gif\" alt=\"Chopsticks Marcosticks - Twirling the top chopstick - Snapping air with max wide-open angle, while the bottom chopstick is held immobile by the left hand - IMG_3620\" class=\"wp-image-862\"\/><\/a><figcaption>Twirling the top chopstick<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p>Rolling of the top chopstick can be better appreciated from a front view of the hand.

Note how the thumb tip appears to \u201cmove\u201d across the surface of the stick. But in reality, it \u201cmeshes\u201d with the surface as if it sported gear teeth. By meshing and locking onto stick surface, the thumb tip is able to roll the stick for 90\u00b0 around its longitudinal axis. This 90\u00b0 rolls can be clearly seen between the closed posture on the left, and the open posture on the right.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:84%\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Flattened-thumb-pose-for-Standard-Grip-chopsticks-posture-front-view-showing-planetary-gears-IMG_7151-IMG_7152-closeup.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"482\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Flattened-thumb-pose-for-Standard-Grip-chopsticks-posture-front-view-showing-planetary-gears-IMG_7151-IMG_7152-closeup-1024x482.jpg\" alt=\"Flattened thumb pose for Standard Grip, seen from the front to illustrate rolling of top stick from closed to open posture, as planetary gears - close-up\" class=\"wp-image-3823\" srcset=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Flattened-thumb-pose-for-Standard-Grip-chopsticks-posture-front-view-showing-planetary-gears-IMG_7151-IMG_7152-closeup-1024x482.jpg 1024w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Flattened-thumb-pose-for-Standard-Grip-chopsticks-posture-front-view-showing-planetary-gears-IMG_7151-IMG_7152-closeup-300x141.jpg 300w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Flattened-thumb-pose-for-Standard-Grip-chopsticks-posture-front-view-showing-planetary-gears-IMG_7151-IMG_7152-closeup-768x361.jpg 768w, https:\/\/marcosticks.org\/wp-content\/uploads\/2020\/12\/Marcosticks-Flattened-thumb-pose-for-Standard-Grip-chopsticks-posture-front-view-showing-planetary-gears-IMG_7151-IMG_7152-closeup.jpg 1343w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption>Rolling of top stick from closed to open posture, as planetary gears &#8211; close-up<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><\/div>\n<\/div>\n\n\n\n<p>As shown, rolling of the top chopstick is how the hand and its fingers actually extend chopsticks open, and clamp them closed. But this is a counterintuitive concept. Most adult learners will intuitively attempt to apply the principle of third-class Archimedean lever to the top chopstick, and try to pry it down with index and middle fingers, against the thumb, as shown below. Note how the chopstick does not roll, and its flat face grinds against the thumb pad. This is evident, because the position of the chopstick remains unchanged with respect to the thumb pad, from the open posture (leftmost) through the closed posture (rightmost).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"320\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-1024x320.jpg\" alt=\"\" class=\"wp-image-10140\" srcset=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-1024x320.jpg 1024w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-300x94.jpg 300w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-768x240.jpg 768w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-1536x480.jpg 1536w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Chopstick-tips-wont-pinch-unhappy-third-class-lever-Sequence-u_iiRaz0r-Side-1-video_sf1-2048x641.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption>Unhappy grip with lack of chopstick rolls &#8211; top chopstick being pivoted like a third-class lever<\/figcaption><\/figure>\n\n\n\n<p>The image shown below left illustrates the same issue.

The curvature of the hyperextended thumb tends to push the rear part of the bottom chopstick further into the crotch between the thumb base and the palm. This makes the 1-on-2-support for the bottom chopstick less stable. And it affects the angle of the bottom chopstick, making its tip pivot upward and outward, thus compounding the issue at hand, where tips can&#8217;t be made to meet.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"263\" src=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-closed-posture-u_iiRaz0r-Side-2-video_s1_FRD-1024x263.jpg\" alt=\"\" class=\"wp-image-10110\" srcset=\"https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-closed-posture-u_iiRaz0r-Side-2-video_s1_FRD-1024x263.jpg 1024w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-closed-posture-u_iiRaz0r-Side-2-video_s1_FRD-300x77.jpg 300w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-closed-posture-u_iiRaz0r-Side-2-video_s1_FRD-768x197.jpg 768w, https:\/\/marcosticks.org\/wp-content\/uploads\/2022\/05\/Marcosticks-Why-cant-I-chopstick-Chopstick-tips-wont-pinch-unhappy-vs-happy-closed-posture-u_iiRaz0r-Side-2-video_s1_FRD.jpg 1305w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>Hyperextended thumb (left) vs regular Caswellian thumb (right)<\/figcaption><\/figure>\n\n\n\n<p>Hyperextension is only an obstacle to be overcome, however.
