If You Can Sharpen A Drill Bit You'll Always Have The Right Size Drill Bit For The Job.
Unless you forget to put them away where they can be found or you loose them.
This is a skill that is easy to acquire and all you need is a bench grinder.
There are different kinds of grinding wheels you can get for a grinder. I like a fine grit witch is fairly soft, It wears away fairly fast but it also doesn't heat up the steel you are grinding as fast as the harder stones do.
Watch and learn how it's done.
