根(gen)據棒(bang)(bang)(bang)球(qiu)(qiu)規則(ze)的規定,球(qiu)(qiu)棒(bang)(bang)(bang)必(bi)須為平滑之圓(yuan)型棒(bang)(bang)(bang),最粗的部(bu)分(fen)(fen)(fen)直徑不(bu)(bu)(bu)得(de)(de)大於(wu)2.75英(ying)(ying)吋(cun)(cun)(七公(gong)(gong)分(fen)(fen)(fen)),長度(du)不(bu)(bu)(bu)得(de)(de)超過(guo)(guo)42英(ying)(ying)吋(cun)(cun)(106.7公(gong)(gong)分(fen)(fen)(fen)),須用一(yi)根(gen)木材(cai)制成(cheng)。以(yi)(yi)合(he)成(cheng)方式(shi)制造(zao)之球(qiu)(qiu)棒(bang)(bang)(bang),在沒有獲(huo)得(de)(de)比(bi)(bi)(bi)賽(sai)(sai)主辦單位(wei)(wei)認(ren)可之前,於(wu)正式(shi)比(bi)(bi)(bi)賽(sai)(sai)中不(bu)(bu)(bu)得(de)(de)使用。由(you)金屬、木片(pian)或竹(zhu)片(pian)接合(he)制成(cheng)之球(qiu)(qiu)棒(bang)(bang)(bang),如(ru)果(guo)獲(huo)得(de)(de)比(bi)(bi)(bi)賽(sai)(sai)主辦單位(wei)(wei)認(ren)可,則(ze)準予(yu)使用。球(qiu)(qiu)棒(bang)(bang)(bang)凹頭的部(bu)分(fen)(fen)(fen),深度(du)必(bi)須在一(yi)英(ying)(ying)吋(cun)(cun)(2.54公(gong)(gong)分(fen)(fen)(fen))之內,寬度(du)不(bu)(bu)(bu)得(de)(de)超過(guo)(guo)兩(liang)英(ying)(ying)吋(cun)(cun)及小於(wu)一(yi)英(ying)(ying)吋(cun)(cun)(5.08公(gong)(gong)分(fen)(fen)(fen)~2.54公(gong)(gong)分(fen)(fen)(fen))。凹狀(zhuang)部(bu)分(fen)(fen)(fen)直徑必(bi)須為曲線狀(zhuang),不(bu)(bu)(bu)可以(yi)(yi)附著其他任何物質。球(qiu)(qiu)棒(bang)(bang)(bang)的握把位(wei)(wei)不(bu)(bu)(bu)得(de)(de)超過(guo)(guo)18英(ying)(ying)吋(cun)(cun)(從棒(bang)(bang)(bang)端起45.72公(gong)(gong)分(fen)(fen)(fen)以(yi)(yi)內),握把部(bu)分(fen)(fen)(fen)得(de)(de)包(bao)扎或使用任何材(cai)料(liao)處理(包(bao)括(kuo)用松(song)(song)脂等)使適(shi)合(he)掌握,但任何使用之村料(liao)包(bao)括(kuo)松(song)(song)PINE TAR),裁(cai)判(pan)員認(ren)為有超越18英(ying)(ying)吋(cun)(cun)之限制,則(ze)該(gai)球(qiu)(qiu)棒(bang)(bang)(bang)於(wu)比(bi)(bi)(bi)賽(sai)(sai)時不(bu)(bu)(bu)得(de)(de)使用。非經比(bi)(bi)(bi)賽(sai)(sai)主辦單位(wei)(wei)之認(ren)可,於(wu)比(bi)(bi)(bi)賽(sai)(sai)中不(bu)(bu)(bu)得(de)(de)使用著色(se)球(qiu)(qiu)棒(bang)(bang)(bang)。
復合(he)(he)球棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)材質(zhi)為(wei)白楊木、楓木與竹片聚合(he)(he)壓(ya)縮而(er)(er)成,也有人稱之為(wei)「壓(ya)縮棒(bang)(bang)(bang)(bang)(bang)(bang)」、「合(he)(he)成棒(bang)(bang)(bang)(bang)(bang)(bang)」、甚至(zhi)「竹棒(bang)(bang)(bang)(bang)(bang)(bang)」。由於復合(he)(he)球棒(bang)(bang)(bang)(bang)(bang)(bang)融(rong)合(he)(he)了(le)木棒(bang)(bang)(bang)(bang)(bang)(bang)與鋁(lv)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)優點(dian),彈性較(jiao)佳而(er)(er)且不(bu)易斷裂,揮擊時(shi)(shi)的(de)(de)(de)力(li)道(dao)其實不(bu)會輸給(gei)鋁(lv)棒(bang)(bang)(bang)(bang)(bang)(bang),所(suo)以(yi)在一般國(guo)際正(zheng)式比賽(sai)(sai)場合(he)(he),通(tong)常都是不(bu)被(bei)允許使用(yong)(yong)的(de)(de)(de);不(bu)過由於國(guo)際棒(bang)(bang)(bang)(bang)(bang)(bang)球總會積極推展國(guo)際賽(sai)(sai)事全面改(gai)用(yong)(yong)木棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)政策之下,復合(he)(he)球棒(bang)(bang)(bang)(bang)(bang)(bang)已經被(bei)視為(wei)全面改(gai)用(yong)(yong)木棒(bang)(bang)(bang)(bang)(bang)(bang)前的(de)(de)(de)過渡球棒(bang)(bang)(bang)(bang)(bang)(bang),在國(guo)內三(san)級(ji)棒(bang)(bang)(bang)(bang)(bang)(bang)球比賽(sai)(sai)中,球棒(bang)(bang)(bang)(bang)(bang)(bang)當然(ran)不(bu)可能是純(chun)「鋁(lv)」所(suo)制(zhi)成,通(tong)常是以(yi)合(he)(he)金成份為(wei)主。鋁(lv)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)使用(yong)(yong)已經日(ri)漸式微(wei),在重(zhong)要的(de)(de)(de)國(guo)際比賽(sai)(sai)當中,幾(ji)乎已經看(kan)(kan)不(bu)到了(le);在國(guo)內的(de)(de)(de)三(san)級(ji)棒(bang)(bang)(bang)(bang)(bang)(bang)球比賽(sai)(sai)中,有時(shi)(shi)仍然(ran)看(kan)(kan)得到鋁(lv)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)身影。
1.若材質(zhi)強(qiang)度高 - 硬度/韌性(xing)高,傳到球的力(li)道較(jiao)直接(jie),能量損耗較(jiao)少,此謂棒子的彈性(xing)系數高;
2.擇材質彈性低(di) - 較(jiao)(jiao)硬的(de)東西,就比(bi)較(jiao)(jiao)不那么flexible,而(er)且回到手掌(zhang)的(de)震動較(jiao)(jiao)大,這(zhe)可(ke)以理解;
3.在此(ci)同時 - 棒(bang)子比較耐用不易斷。
球 棒木(mu)(mu)質不(bu)比手(shou)套皮革嬌嫩,倒是(shi)木(mu)(mu)、竹材質都(dou)怕濕,保持干(gan)爽的(de)細節(jie)要注(zhu)(zhu)意。新棒會上(shang)漆,不(bu)只是(shi)印logo、討個亮麗外觀,主要能防濕氣,如同所(suo)有木(mu)(mu)制品(pin)一(yi)般。球棒打久會磨擦掉漆,此時(shi)更應該注(zhu)(zhu)意保存時(shi)的(de)防濕。
