墨斗
墨斗，又称线墨，为木工用以弹线的工具，在泥、石、瓦等行业中为不可或缺之工具，传为鲁班发明。
此工具以圆斗状的墨仓贮墨，线绳由一端穿过墨穴染色，已染色绳线末端为一个小木钩，称为「班母」，传为鲁班之母亲发明。
班母通常离地面约一吋。固定之后，将已染色线绳向地面弹动，工地以此为地平直线标准。又可以班母固定于高处，墨斗悬垂，以墨斗之重量作墬力，将已染色线绳向壁面弹动，以此为立面直线标准。

Chalk line 墨斗
A chalk line or chalk box is a tool for marking long, straight lines on relatively flat surfaces, much farther than is practical by hand or with a straightedge.
It is an important tool in construction and carpentry, the working of timber in a rough and unplaned state, as it does not require the timber to have a straight or squared edge formed onto it beforehand.
