These crystals are ideal for the creation of lightsabers , as they focus the energy released from a saber ' s power cell into the tight , blade - like beam 这种水晶是制造光剑的理想原材料，它们把从光剑的能量电池中释放出的能量聚焦成为紧密的、剑刃般的光束。
From the stalk it feels like crescent block and wide stalk jian without curved mortise . the head which was forged with the whole was cut . this kind of jian mostly has strong blade 观茎后感觉应是失了上弯型铆固式类似月牙剑挡的宽茎剑，原本一体锻造的剑首被截去，这类剑刃质普遍都相当刚强。
This sword , hundreds years till now , has never been polished . you can look at the pics , the blade has no abrasion . we can say it ' s a furnishings since the ancient time . it ' s my personal opinion , hope comment 这把剑可以说从出生到现在几百年没有上过磨石,各位可以看图,剑刃无一点磨损的样子,可以说此剑从古到今就是个摆设而已,一已之见,望赐教
In addition to the long hilt that gave the user high leverage , the blade was very sharp and relatively thin for the length , making the sword nimble for its size . in fact , one could wield this sword with single hand without many difficulties 除了长长的手柄给予了用者很大的杠杆力之外，剑刃也非常锋利，以它的长度来说也算薄，因此剑的活动以双手剑而言是很灵巧的。
The blade is 6mm thick at the base with little distal taper to 5mm just before tapering to the point . this gives the sword a very stiff blade to allow strong thrusts and almost zero loss of power transfer during sword binding movements 这枝剑的根部厚6mm ，一直到剑尖也仍然厚5mm ，不太出现刃厚渐薄的情况，令它的剑刃非常坚挺，刺时既可以准确无误，与对手?剑时也不会被剑刃的弹性浪费掉用者的任何力气。
The basin - shaped guard caught not only the blood flowing down the blade during combat , but also incoming attacks from both along the edges and along the spine , while the non - angular design on all the fittings prevent producing any hard feeling to the sword hand and wrist during motions 另外，剑的护手设计也很实用和符合人体工学。像盆形的护手除了可以盛著从剑刃流下血之外，也可以截下沿著锋口或剑脊滑下来的刀剑。
The blade ' s color depends on the nature of the jewel it springs from , and while its length is fixed in the case of a single jewel lightsaber , lightsabers equipped with multiple crystals can have their length varied by rotating a knob that allows the focusing crystal activator to subtly modify the refraction pattern between the gems 剑刃的颜色取决于源晶体的性质，尽管单晶体光剑的剑刃长度是固定的，装备有复合水晶的光剑可以通过旋动一个旋钮来移动聚焦晶体，来精确地调整晶体间的折射方式，从而随意改变刃长。
