    David Rees runs a truly distinctive business． He charges customers ﹩15 to sharpen their pencils to perfections， using a variety of tools．

I know what you're thinking ﹣ is this a joke？ The 39﹣year﹣old gets asked that question a lot． To clarify everything， he even created a special section on his website telling everyone he's actually providing a real service．

You can supply your own pencil or you can have Rees sharpen one of his own favorite 2B pencils． After that， he mails it to you in a display tube with the shavings in a separate bag， and an authentic certificate which just happens to mention the pencil is so sharp as to be a dangerous object．

To achieve the desired result， the master sharpener uses all kinds of tools， including general sandpapers， pocket knives and even a special﹩450 sharpening machine． "It depends on what the customer wants to use his/her pencil for，" he says． "That determines the most appropriate pencil﹣sharpening technique． Some customers buy pencils as inspirational symbols while others buy them because of their special memories of classic 2B pencils．"

﹩15 to have a pencil sharpened is a bit expensive though， right？ You're not the only one who feels that way， and David's unique business has really angered lots of people， who talk of inequality in America， saying it is so insane for the wealthy to pay﹩15 to sharpen a pencil． But others will say， "This is just our urge to put an end to the welfare state because new ideas arise along with the business．"

David admits his trade is sort of unusual． But there are those who actually value his service， as proven by the over 500 orders he has gotten．
