Resin Bonded Diamond Sharpening Stones
Professional-grade resin bonded diamond sharpening stones, formulated and branded by a sharpener, for sharpeners. Every grit. One standard. Zero compromise.
Shop the CollectionEdgeWorks Knife Studio started as a YouTube channel dedicated to the art and science of knife sharpening. After years of testing stones from around the world, I worked directly with a manufacturer testing a line of resin bonded diamond stones that meet my personal standards — aggressive cut, flat surface, consistent grit, and a price that doesn't insult you.
These aren't generic rebadged stones. The formulation, the bond hardness, the grit distribution — all of it meets what I am looking for in a stone. If it doesn't perform, I don't sell it.
In-stock items ship within 48 hours of confirmed payment. Pre-order items are queued for the next inbound shipment — approximately 20–30 days to reach our facility, then shipped directly to you.
Pre-orders ship to your door within 1 day of arrival in my posession. Stones ship direct from overseas manufacturing to me, and I inspect after receipt to ensure nothing happened in transit, then right out to you! Worth the wait.
Once inventory is established, orders will ship from domestic stock moving forward. Pre-order customers get priority on future restocks.
