The clippers are precision instruments designed to brilliantly clip nails. This seems a little strange, but our hands are the tools with which we sculpt perfection. What if Michelangelo had used a dull chisel? We need to keep our hands in pristine condition, if we are going to use them to showcase our talents and dedication. Roberto Giobbi makes an excellent point about superbly groomed hands. I cannot stress enough that if people are going to be looking at our hands, they should be impressed by what they see, regardless of skill. It is an example of professionalism that should not be overlooked.
Sorry for he rambling.
