Built for chef's knives, santokus, meat slicers, and paring blades.
Resets heavily dulled edges and establishes a clean, symmetrical 20° bevel in 4–5 pulls.
Fine diamond-coated rods smooth out microscopic nicks on hard German and Japanese steel.
Hones and polishes the edge so your blade glides through ripe tomato skin without crushing.
Full-length silicone base pads grip marble, wood, and granite while keeping your hand safely away from the blade.
Freehand whetstones take practice and soaking. Inside the brushed stainless head of the Cosari EdgePro X1, all three V-slots lock your blade at a precise 20° angle automatically.
Dull blades slip off onion and tomato skins. A ceramic-polished edge bites instantly with zero downward force, making everyday dinner prep faster and safer.
When you finish sharpening, unclip the 3-stage stainless cassette in one second and rinse away metal dust under running water.

Draw dull blades 4–5 times through Slot 1 (Tungsten) and Slot 2 (Diamond) with light pressure.
Pull 3–4 times through Slot 3 (White Ceramic) for a burr-free razor finish—great for weekly touch-ups.
Wipe the blade with the free microfiber cloth and enjoy paper-thin tomato and meat slices.
I was about to buy a new knife block. Five pulls through slots 1, 2, and 3 and my old chef's knife glided through ripe tomatoes under its own weight. The red rubber base doesn't budge a millimeter on our wood counter.
I could never hold a steady angle on a whetstone. With the Cosari, you set it on the granite, hold the ergonomic handle, and pull. Even our small paring knives cut like brand new.
I bought this for our cabin and honestly prefer it over the expensive rolling sharpener we have at home. The free cut-resistant glove is a great touch.
Just flip it 180 degrees, hold the handle with your right hand, and pull with your left. Feels completely stable and safe.
Being able to snap out the stainless slot block and rinse off the metal dust under the faucet is brilliant.
You don't realize how dull your knives were until you use this. Fast shipping and rock-solid build.
After the initial 3-stage sharpen, I just do three quick passes through Stage 3 every Sunday before meal prep.
Gives you total confidence when sharpening larger butcher and chef blades.
Put a razor edge on my folding pocket knife in six strokes.
For $29.99 every knife in our kitchen cuts like day one and it fits right in the cutlery drawer.

Yes. Simply flip the symmetrical sharpener around, grip the ergonomic handle with your right hand, and pull with your left.
