None better.

There are a great deal of cheap ones that look similar, but make sure they're an authentic NICHOLSON set and you'll not be disappointed. I've had my set so long, mine came with the little plastic file handles. I couldn't find any with the handles to show you, but these files are still the ones.
Like this, but mine came gray already on the files. Not necessary, but more comfortable than the straight shaft if you have to use them for a couple hours.
