Waterstones as we know them today vary in size, type, material, origin and quality. Natural waterstones have been mined and used in their natural form for several thousands of years in Japan. They are newer to western woodworkers though, who traditionally have used oilstones. The first modern synthetic stone made in the US was by Norton Abrasives in 1993.
These videos are an introduction to the use and care of waterstones, just one type of whetstone. My acting hasn't improved any, but hopefully the video is at least marginally informational. If you have any questions or want to see a tutorial on something specific email me and I'll see what I can do. Thanks for watching (like how I assumed you'd actually watch these?).
