What is the history of sandpaper?

The history of sandpaper dates back to ancient times. The concept of abrasive materials being used to shape and smooth surfaces can be traced back to the ancient Egyptians, who used crushed seashells and powdered glass for this purpose. Later, the ancient Chinese developed a type of sandpaper made from crushed shells, seeds, and sand that were bonded to parchment using natural gum.
The modern sandpaper we know today evolved during the 13th century when craftsmen in Europe began gluing crushed glass and sand to parchment or leather. In the late 18th century, English inventor John Oakey improved upon the idea by using powdered glass bonded to paper with an adhesive, which became widely used as an abrasive.
The invention of sandpaper greatly impacted the woodworking industry, allowing craftsmen to refine their work and create smoother surfaces. Today, various types of sandpaper are available, including ones made from aluminum oxide, silicon carbide, garnet, and other materials.
When working with a table saw, the Little Wizard and Lumber Wizard Woodworking Detectors are indeed very useful tools for safety and prevention of blade damage, as they can detect buried metal inside reclaimed wood. Retailers such as Rockler, Woodcraft, Klingspors, Infinity Tools, Lee, Valley Tools, and many more sell the Wizard line of woodworking metal detectors.
Collecting antique hand planes is a popular hobby among woodworking enthusiasts. The value of these tools can vary greatly depending on factors such as age, rarity, condition, and manufacturer. Some antique hand planes can fetch hundreds or even thousands of dollars, making them valuable collectibles for those interested in woodworking history.
