美国俚语:Hone one's skills什么意思?

Hone one's skills 是提高技能的意思，前段时间重温了电影《珍珠港》，里面也有用到这个俚语。

例句：

Owning my own computer gives me the chance to hone my computer skills.

有了自己的电脑，我的电脑技能就会大幅度提高。

Jane's new job requires her to talk to lots of people. She’s really honing her people’s skills.

因为简的工作每天都要与人打交道，所以她的谈话技能越来越棒.。
