Abstract
写字、绘图离不开铅笔，以往的旋笔刀削出的笔头总是不尽满意，折叠笔刀使用时先将铅芯削出后再用刀口刮，使用起来很不方便。本实用新型是在折叠笔刀基础上略加改进，将刀片的两个侧面做成锉纹，使削、磨于一整体，即不增加成本，又使其增添一新的功能，给写字、绘图带来很大方便。
Description
本实用新型是有关削铅笔用的文教用品。
使用铅笔写字、绘图对笔头的形状有一定的要求，以往的旋笔刀削出的笔头短尖，且易折断。用折叠笔刀先将铅芯削出后再用刀口刮也很不方便，有时不得不用砂纸磨成需要的形状。本实用新型在折叠笔刀的基础上将刀片的两个侧面做成锉纹，即不影响笔刀的切削作用，又使其增加了磨铅笔芯的功能，给写字、绘图带来很大的方便。
