工欲善其事，必先利其器: Sharpen Your Tools

What does it mean?

工欲善其事，必先利其器 (gōng yù shàn qí shì, bì xiān lì qí qì) is commonly translated “to do good work, one must first sharpen the tools.” 工 is a craftsman or worker, 善其事 means to do the work well, and 利其器 means to make the tools sharp or effective.

Where it comes from

The line is from the Analects · 论语, Wei Ling Gong 15.10. In the fuller passage, the image is applied to learning from worthy people and forming good relationships, not only to literal tools.

How to use it

It fits study, training, project preparation and professional development. The “tool” can be equipment, knowledge, a checklist or a support system. The saying does not guarantee good work merely because preparation happened.

What it does not mean

It does not mean buying more equipment is always the answer or that preparation replaces action. It also does not promise success.

Common mistakes

• Reading 器 only as a physical tool.
• Using the phrase to justify endless preparation.
• Separating the second clause from the first and losing the cause-and-effect structure.

The source context

The line comes from the Analects · 论语, Wei Ling Gong 15.10. In the fuller passage, the image of sharpening tools is connected to learning from worthy people and forming good relationships. The “tool” can be knowledge, preparation, equipment or support, not only a physical instrument.

Preparation is not endless delay

The saying supports preparation before action, but it does not mean that buying more equipment or planning forever will guarantee good work. Preparation should serve execution and be proportionate to the task.

Use in study and design

It is useful for study notes, training material and project preparation. Keep both clauses together if the cause-and-effect structure matters. The shorter 工欲善其事 is often quoted, but the full line makes the logic clearer.
