周身刀－冇張利 | “A Knife All Over, Yet Not One Blade Is Sharp” — The Cantonese Saying About Being Jack of All Trades but Master of Nonet｜廣東話歇後
「周身刀，冇張利」係一句非常經典嘅廣東話歇後語，用嚟形容一個人好似樣樣都識少少、樣樣都有涉獵，但真正做到出色或者專精嘅地方卻唔多。喺香港舊時社會，尤其係基層勞動環境入面，人人都要識多門手藝先搵到食，但如果每樣都只係半桶水，最後反而會令人覺得「冇樣掂」。呢句說話表面講刀，其實係借刀來比喻能力與本事，語氣帶少少嘲諷，但亦帶有現實感。現代社會之中，無論職場、創作、學習甚至社交圈，都經常會聽到有人用呢句說話評論一啲「樣樣都做但樣樣都唔精」嘅人。
“周身刀，冇張利” is a well-known Cantonese saying that paints a vivid picture of someone who seems to possess many skills, yet excels at none of them. Literally referring to a person covered in knives but lacking a single sharp blade, the phrase humorously criticizes those who spread themselves too thin. In traditional Hong Kong society, especially among working-class communities, versatility was often necessary for survival. However, being able to do many things poorly was never as respected as mastering one craft properly. Today, the expression remains highly relevant in workplaces, education, business, and even online culture, where people often try to multitask endlessly without developing true expertise in any particular area.
意思
「周身刀，冇張利」最核心嘅意思，就係指一個人雖然識好多嘢，但全部都唔夠深入，缺乏真正拿手或者突出嘅能力。呢句說話有時會用嚟形容工作上「樣樣掂少少」嘅人，例如識剪片、識設計、識寫文案、識做生意，但每樣都只停留喺普通水平，結果真正遇到高要求時就難以勝任。廣東話文化入面，刀通常代表本領、技術或者能力，而「周身刀」就代表擁有好多工具；不過「冇張利」就指出所有刀都唔夠鋒利，即係無一樣真正厲害。呢句歇後語之所以流行，正正因為佢反映咗人生入面一種常見矛盾：到底應該做多方面發展，定係集中火力鑽研一樣？有啲人認為多技能係優勢，可以增加生存能力；但亦有人覺得，如果永遠只係淺嘗即止，就好難建立真正競爭力。尤其係現代資訊爆炸年代，好多人不停學新嘢、跟潮流、轉方向，但缺乏長時間沉澱，最終變成「識好多，但冇一樣特別強」。所以呢句話有時唔單止係批評，亦係一種提醒：與其周圍分散精力，不如先磨利其中一把刀。
English Version
The Cantonese saying “周身刀，冇張利” describes a person who appears to possess numerous talents or abilities but lacks genuine mastery in any one area. It reflects the idea of being a “jack of all trades, master of none.” The metaphor is simple yet powerful: a body full of knives sounds impressive at first, but if none of those knives are sharp, they become far less useful. In daily life, the phrase is often used to describe people who constantly jump between hobbies, careers, or projects without dedicating enough time to truly refine their skills. Someone may know basic graphic design, video editing, coding, writing, marketing, and business strategies, yet fail to stand out professionally because their abilities remain superficial. The expression also highlights an important cultural value in Cantonese society: depth and craftsmanship are respected more than shallow versatility. Historically, skilled workers, craftsmen, chefs, and tradesmen earned admiration through mastery built over years of practice. Modern society, however, encourages people to multitask and chase trends rapidly, leading many to develop wide but shallow skill sets. This saying therefore carries both criticism and wisdom. It warns against spreading oneself too thin and reminds people that true excellence often comes from patience, focus, and repeated refinement. At the same time, it acknowledges the tension between adaptability and specialization in a fast-changing world.
用法
日常生活入面，「周身刀，冇張利」通常用嚟帶點幽默咁評論一個人。例如朋友成日話自己識好多技能，但最後做乜都唔算突出，就有人會笑佢「周身刀，冇張利」。職場上亦常見，例如一間公司有人樣樣工作都掂少少，但真正要負責重要項目時卻欠缺專業深度。父母有時亦會用呢句話提醒子女，學興趣班唔係問題，但如果不停轉換、樣樣半途而廢，就難有真正成果。語氣通常偏戲謔，但未必完全負面，有時亦帶少少自嘲意味。
English Version
In conversation, this phrase is commonly used in a humorous or mildly sarcastic way. People might say it about a friend who constantly claims to know many things but never becomes truly skilled in any of them. In workplaces, it may describe employees who can handle many small tasks yet lack the expertise needed for major responsibilities. Parents may also use the saying to remind children not to give up too quickly when learning music, sports, or creative skills. Although the expression sounds critical, it is often used playfully and can even be self-deprecating when someone jokes about their own lack of specialization.

Keung had always been curious about everything. One month he learned guitar, the next he became interested in sketching, and shortly afterward he was obsessed with photography. During secondary school, he joined drama club, basketball team, computer workshops, and even a magic society. His classmates admired him because he seemed talented in many areas. However, there was one problem — he rarely stayed committed long enough to master anything. Whenever the excitement faded, he quickly moved on to another hobby. After graduation, Keung entered the workforce with a resume filled with impressive-looking skills. At interviews, he confidently described all the things he had tried before. Employers were initially interested because he appeared versatile and adaptable. Yet once real projects began, weaknesses slowly surfaced. His design work lacked polish, his reports lacked depth, and his communication skills lacked confidence. He could contribute a little to everything but was never trusted with the most important responsibilities. One day, during preparations for a major company project, his manager assigned key tasks to specialists while asking Keung only to assist with miscellaneous work. Frustrated, he complained that he knew how to do many things. An older colleague smiled during lunch and said, “You’re like someone carrying knives everywhere, but not a single blade is sharp.” The comment stayed in Keung’s mind for days. Eventually, he realized the problem was not a lack of talent, but a lack of focus. From then on, he decided to specialize in video editing. He spent years practicing, studying techniques, and taking freelance projects after work. Slowly, his skills became sharper and more respected. Years later, he became one of the company’s top editors. Whenever someone mentioned the old saying again, Keung simply laughed, knowing he had finally sharpened at least one blade properly.
結語
「周身刀，冇張利」之所以流傳至今，正因為佢貼近人生現實。人可以有好多興趣，但真正令人發光發亮嘅，往往係長時間累積出嚟嘅專注與深度。識得多未必係壞事，但如果能夠喺其中一方面真正磨練出實力，人生往往會走得更遠。
English Version
The enduring popularity of “周身刀，冇張利” comes from how accurately it reflects human nature and modern life. Having many interests is not a weakness, but without dedication and depth, talent can remain scattered and unfocused. In the end, real excellence often comes from sharpening one meaningful skill until it truly stands out.
