學習取竹與剖篾-高階/How to select bamboo and make strips-Advanced level

本片使用桂竹示範劈分260cm長的竹稈。 This video demonstrates the splitting of 260cm-long Makino bamboo culms. 初學剖長竹的朋友須注意在劈分時，手不要貼著裂縫避免被夾進去，保持手與竹子的距離才不會受傷。 When beggining to learn how to split long bamboo culms, keep your hands away from the slit to avoid getting clamped and injured. 剖長度較長，或口徑較大的竹稈，建議使用大刀加篾橋(與刀片鋒等長的竹片)，會比較省力；若用小劈刀（日本刀）剖長的竹稈，過節時要轉刀柄，過多扭的動作比較容易造成手腕發炎。 When splitting longer or larger culms, it is recommended to use a bigger hatchet and a "bridge" - a piece of bamboo with the same length of the blade. Smaller hatchet such as the Japanese ones require twists when cutting through nodes, and could cause arthritis in your wrist after intense use. 相對於用薄刀片的小把刀，大刀加篾橋主要作用是剖厚度時，方便撐開竹片。大刀的刀面比較寬，因此支撐竹片的面積也比較多，因此剖起來會比較平整。 It is easier to slice the bamboo strips with a bigger hatchet and a bridge than with a smaller knife with thinner blade. Bigger hatchet has a wider belly of blade to support the bamboo strip, so the slices will also be smoother with even thickness. 剖長竹時，要充分運用拋物線原理，因此建議利用長板凳作為支點，一方面穩定竹片讓他不要亂晃，一方面分散竹子的重量，讓手不要這麼吃力。 Support longer bamboo culms and strips with a bench to keep them steady and distribute the weight on your arms and wrists. 剖開長竹另一種省力的方法是用劈分器，但如果很要求不浪費材料，則不建議使用，因為用劈分器會產生較多的邊材。 The "bamboo splitter" is another way to split with less effort, but is not recommended as it leaves behind more excess bamboo. 舉例說明：一支圓周210mm的竹稈，設定篾寬為６ｍｍ。 A.使用劈刀：對剖後為周長105mm，可剖17條，會有寬3mm的廢料(6*17+3)=105(mm) B.使用1/4劈分器：剖開後，每片圓周是52.5，可剖成8條，半個圓為16條，每1/4圓周的竹片會有4.5mm廢料。 For instance, when splitting a bamboo culm with a circumference of 210mm for strips with a 6mm width, a hatchet gives you 2 halfes measuring 105mm, each splitting into 17 strips and an excess measuring 3mm in width (and 6mm in total); while a quarter splitter gives you 4 quarters measuring 52.5, each splitting into 8 strips and an excess measuring 4.5mm in width (and 18mm in total).
