It is equal to abandoned this part of material of nib lost and sharpens the saw-dust lost with the wooden pencil in fact, Because in 95%, the lead clothing pencil the raw materials utilization ratios of it material-saving the wrapping up core lead part removes the space of blind hole part of filling in backs end of pencil stub that are taken up of post of handle of pencil, The plumbaginous clothing material sharpens the saw-dust equivalent of material lost to consume with the wooden pencil basically, The pencil utilization ratio of raw materials produced with the timber is in 30-35%, a finished product pencil can only use two-thirds in using, Back one-third is abandoned, so the material-saving pencil is still pencil province of material-saving raw materials compared with wooden pencil.

被弃掉的笔头这部分材料实际上是与木制铅笔削掉的木屑是相等的，因为，节材铅笔它的原材料利用率在95%，铅衣包铅芯部分除去铅笔柄柱塞所占的铅笔头后端的盲孔部分的空间，铅衣材料基本和木制铅笔削铅衣削掉的木屑材料等量耗费的，而用木材生产铅笔的原材料利用率在30%-35%，一支成品铅笔在使用中只能使用三分之二，后三分之一被弃掉，所以节材铅笔与木制铅笔相对比还是节材铅笔节省原材料。
