Keep yourself sharp by taking time to relax, recharge, and renew

Many people sharpen their drill bits on a grinder. It's tricky to describe how and I'd advise asking an expert to actually show you, or second best, look at some Youtube videos on the subject.

to sharpen (a knife or any blade) is "aiguiser" in French. To sharpen a pen is "tailler un crayon".

The verb of sharpness is sharpen.

As in "to sharpen something".

It is wiser to sharpen your wit, instead of your tongue.

I would like to sharpen my pencil, please.
