高尔夫球杆的几点学问
许多初入门的高尔夫球友，对球杆基本规格如lie、swing-weight、bounce…等名词常感不知所云，往往无法从这些规格说明中看出球杆是否合用，更谈不上利用不同的规格设定来选择球杆，“看”出球杆的表现。下面就来和我一起看看高尔夫球杆的几点学问吧。
杆面角
所谓“Loft”杆面角，是指球杆杆面与垂直线间的角度。球友可在木杆杆底看到10。、15等数字，这就是loft杆面角。近来球杆设计人员为距离不足的球友，采用“强势角度”来提高球友的铁杆击球距离，以不同二套球杆之7号铁为例：A组的loft是常见的35。，B组的loft采较强势的33。(可击出较长距离)，故距离不足的球友在选购时便可选B组，以改善成绩。
杆底角与杆面后移值
杆底角“Lie”指将球杆拿起杆底平放，杆颈至地面的角度。目前各品牌球杆lie是取最大公约数，故绝大多数的球友多可合用；虽说传统设计上lie在“标准情况下”与身高成正比关系，但近来有部分品牌的中高差点球杆，刻意采取较高杆底角的设定，并利用过高的lie在瞄球时趾部跷起产生左拉球的特性(反之则产生右推球)，来形成抵销slice球的“防右曲”设计。同样具防止slice功能的设计为“offset”杆面后移值-是指球杆面后移杆身中心线的程度，offset可延后击球防止slice，惟过多的杆面后移会造成击球迟钝及作球上的困扰。
挥杆重量
许多球友对“Swing Weight”挥杆重量感到疑惑，它是指将球杆水平放置于挥杆重量仪，所测量出杆头和杆身间拉扯的重量。挥杆重量以一个A～E英文字母加上一个0～9数字 来表示，一般球友多使用C8(轻)到D3(重)的球杆。使用挥杆重量较重之球杆虽有助于感觉球头，但研究显示过重的挥杆重量会造成疲惫感，不仅在体力较差 时易失击，且长久使用亦可能造成运动伤害，不可不慎！此外当不同品牌的铁杆组及木杆混合搭配使用时，需注意挥杆重量应尽量保持在二个单位间，以免因挥杆重量相差过多而失误连连。
杆身弹性与曲折点
杆身弹性“Flex”指球杆软硬度，量测方法已由以往利用砝码悬于杆身一端的弹性测试仪，改为较精密的杆身震动频率判读，目前多以L(杆身软弹道高)、A(或M)、R、S(或F)、及X(杆身硬弹道低平)等五级标示，惟各品牌对弹性范围定义不一，选购上须先了解杆身的弹性范围及球友实际挥杆速度 来判断。
此外杆身曲折点“kickpoint”的不同，亦会产生不同的弹道及手感。曲折点指将球杆垂直于地面，由握把底端向下压时杆身最弯曲处，曲折点愈 低的球杆打来愈会有“抽”的感觉弹道亦较高，反之则弹道较低平。
扭力与反弹角
杆身扭力“torque”代表球杆的`刚性，扭力值愈低表示球杆的刚性愈高，击球的安定性愈好；惟低扭力杆身要求的击球实力及能量亦相对较高，否则失击时的反震恐会震伤球友。近年在新工法及新材质应用下，高档纤维杆身不但保有高torque易驾 驭的轻松特性，更在距离效果上有不错表现。
反弹角“bounce”是指杆底与水平面的夹角，反弹角大的球杆(短铁wedge)较“锋利”有助于下斩，反弹角小甚至为负的球杆(长铁)则有助于扫击，而这也是当球入长草区时用反弹角小的长铁会打不出去的原因。
