槌

Tree radical on the left - pictograph of a trunk with branches and roots. Marks 槌 as a wooden implement: a mallet, beater, or drumstick made from a piece of carved hardwood. Sits with 棒 stick, 杆 pole, 椎 club - all wooden striking or grasping tools built on the 木 radical.

Right side 追 supplies the sound - zhuī shifting to chuí, a regular zh/ch retroflex alternation. The 'to chase' meaning has no semantic role; pure phonetic. The same phonetic stem produces 椎 chuí spine/vertebra and 锤 chuí hammer, all reading the same chuí - three different materials (wood, bone, metal) all named with the 追 phonetic for striking implements.
