Machined grooves that catch the light and guide your fingers.
What it is
Fluting is a pattern of parallel grooves cut into a surface, often around a round part, like the channels on a classical column or a watch bezel. It can be made on a lathe or with CNC milling, and the grooves can be straight, angled or spiraled. Groove count, depth and spacing depend on the maker.
How it feels in your EDC
Fluting gives a piece a refined, architectural look, with light and shadow playing across the alternating grooves and ridges. It adds some grip, but it usually feels smoother and less aggressive than knurling. It is common on beads, knobs, pens, spinner rings and edges, where it adds both style and a pleasant tactile rhythm.
Care & aging
The grooves can collect lint and grime with daily carry, so clean them occasionally with a soft brush and mild soap, then dry them well. Over time, the raised ridges may brighten or soften slightly from handling, while the grooves keep their original finish, which can make the pattern stand out even more.
是什么
凹槽纹（Fluting）是切削在表面上的一组平行凹槽，常环绕圆形零件，就像古典立柱或表圈上的槽纹。可以在车床上或用 CNC 铣削完成，凹槽可以是直的、斜的或螺旋的。凹槽数量、深度和间距取决于品牌。
上手感受
凹槽纹让作品带有精致的建筑感，光影在交替的凹槽和棱线上流动。它增加一定握持感，但通常比滚花更顺滑、更温和。常见于珠子、旋钮、笔、陀螺环和边缘，既增添风格，又带来舒适的触感节奏。
保养与老化
日常携带时凹槽会积存棉絮和污垢，偶尔用软毛刷和温和的肥皂清洁，然后彻底擦干。时间久了，凸起的棱线可能因把玩略微变亮或变柔和，而凹槽保持原本的表面，让图案更加突出。
