Crosshatch texture that adds grip and a satisfying tactile feel.
What it is
Knurling is a textured pattern pressed or cut into a surface, usually in straight lines, angled lines or a crisscross diamond pattern. On round parts, it is often made on a lathe with a knurling tool; on flat or complex parts, it can be machined with CNC. The pattern style, depth and spacing depend on the maker.
How it feels in your EDC
Knurling adds grip and a satisfying tactile texture under your fingertips. Fine knurling tends to feel smooth and comfortable, while coarse or deep knurling grips more aggressively. It is common on knobs, beads, spinner rings, buttons and pens, where it improves control and adds a classic machined look.
Care & aging
The grooves in knurling can collect lint, dirt and skin oils over time. Clean it occasionally with a soft brush and mild soap, then dry it well. With long-term handling, sharp knurling may soften slightly and feel smoother. On coated or anodized parts, the raised peaks may wear first and show the metal beneath.
是什么
滚花（Knurling）是压制或切削在表面上的纹理图案，常见有直纹、斜纹和交叉菱形网纹。圆形零件上通常用滚花刀在车床上完成；平面或复杂零件则可以用 CNC 加工。纹样、深度和间距取决于品牌。
上手感受
滚花在指尖下带来握持感和令人满足的触感纹理。细滚花往往顺滑舒适，粗或深的滚花抓握感更强烈。它常见于旋钮、珠子、陀螺环、按键和笔上，既提升操控性，又带来经典的机加工外观。
保养与老化
滚花的凹槽会随时间积存棉絮、污垢和皮肤油脂。偶尔用软毛刷和温和的肥皂清洁，然后彻底擦干。长期把玩后，锐利的滚花可能略微变钝、更顺手。在有涂层或阳极氧化的零件上，凸起的尖峰可能最先磨损，露出底下的金属。
