In this art form, words or patterns can be carved into any of various firm surfaces, such as ivory, dolphin teeth, fruit pits, tortoiseshell, fish scales and coral. Since it is impossible to appreciate the full intricacy of these works with the naked eye, viewers use 20x magnifying glasses.
毫芒雕刻將文字、圖案，刻劃在象牙、海豚牙、果核、龜殼、鱗片、珊瑚之類的堅硬素材上，觀者無法單憑肉眼一窺全貌，須借助 20 倍以上的放大鏡，才能纖毫畢現；雖是極細微字跡，但刀法剛健遒勁饒有帖意、山水景致秀麗宜人、人物衣襟交錯有序，令人嘆為觀止。
