Material removed through a part to save weight or show the inside.
What it is
Skeletonizing means cutting windows or pockets through a part. On spinners it shifts weight toward the rim; on sliders and coins it can reveal magnets, balls or a contrasting inner layer.
Why it matters
It is both a weight decision and a visual one. More cutouts mean lighter parts and more edges, so the quality of the chamfers and edge finish inside each opening matters for comfort.
Also known as: Skeletonised, Cutout, Openwork, 镂空设计.
是什么
镂空就是在零件上切出窗口或凹槽。陀螺镂空可以把重量推向外缘；推牌和响币镂空可以露出磁铁、钢珠或对比色内层。
为什么重要
镂空既关乎重量，也关乎外观。开口越多，零件越轻，边缘也越多，所以每个开口里的倒角和边缘处理决定了握持是否舒服。
