Review on Non-Slip Sharpening Whetstone with Flattening Capability by Jonathan Unruh

I'll add a link to YouTube here, but if searching YouTube doesn't work, then "grindstone". There are many. The one for this exact product is from Culinary Obsession and runs 4.01 minutes. What's still not entirely clear is how to use the guide, but it's not really needed. #how to use a whetstone
