To See The World In A Grain Of Sand

Variants of sandpaper have been around since 13th Century China where they used natural gum to adhere shells, sand and seeds to parchment.  I have also found several references to shark skin, pumice, equisetum hyemale, and several other abrasive materials being used to polish and sand the surfaces of wood and stone.

The nerd in me (okay, so all of me) got all excited when I found out that the concept of sandpaper turned out to have been around for centuries before the first real mass production of "glass paper" by John Oakey in 1833.  There were even written warnings for counterfeit glass paper being sold on the streets of Paris in the mid 1700's.

The first actual patent for sandpaper production was in 1834 by Isaac Fischer, Jr. in Vermont and in 1916 3M invented the first wet/dry sandpaper.  If you would like to read more than you ever wanted to know about the details of sandpaper you should give this engineering article a read C&EN Sandpaper.  Go ahead click it, no one will be the wiser...you know you want to.

These videos cover the basics of sandpaper sharpening or the "scary sharp" method.  I mention a couple of links in the videos which are below.  Please feel free to leave a comment and check them out at the P.H.W. YouTube channel as well (link is below).
