A bad workman always blames his tools.

　　不會撐船怪河彎

　　手藝好的人不太在意工具的好壞，靠的就是一手好技藝!所以，怪工具不夠好的工匠，通常是自己的技術也不太過關。

　　Good workmanship depends no more on the quality of the tools than it does on the way in which they are used, so to blame the tools for the bad workmanship is to attempt to excuse ones own lack of skill.

　　如果有人活兒沒干好，或是輸了比賽，卻賴設備不夠好，你就可以用上這句諺語來影射根本就不是這么回事。

　　If somebody does a job badly or loses in a game and claims that they were let down by their equipment, you can use this to imply that this was not the case.

　　比如以下這些情況：

　　My essay wasnt very good because I had to use someone elses pen.

　　我作文沒寫好，都是因為用了別人的筆。

　　How did you expect me to catch fish with this rod?

　　這么破的魚竿，你還指望我釣上魚來?
