Rolling knife sharpener with dual angle

The Aierlian-01 rolling knife sharpener brings factory-level edge maintenance to home cooks and professional chefs who want consistent results without freehand skill. Its magnetic base holds the blade at a fixed 15 or 20 degree angle while the roller guides the abrasive disc across the edge. The compact bamboo frame measures 5.49 in x 4.6 in x 2.7 in and fits on any countertop.

Upgrade from pull-through and stone systems

This sharpener replaces basic pull-through devices that wear unevenly and water stones that demand practice and flattening. The rolling action keeps the abrasive flat against the bevel at all times, so the angle never drifts. The jump is worth it when you sharpen several knives a week and want repeatable geometry on blades of any steel hardness.

#400 diamond and #3000 ceramic grit capacity

The #400 diamond disc removes metal quickly to set a new bevel or repair chips, while the #3000 ceramic disc polishes the edge to a refined finish suitable for push-cutting tomatoes. Four N42 magnets lock the knife firmly during each pass. The system handles straight blades from paring knives to cleavers but cannot sharpen serrations or scissors.

Questions about this item

How much counter space does the 5.49 in x 4.6 in x 2.7 in sharpener need?

The rolling sharpener measures 5.49 in long, 4.6 in wide and 2.7 in high, so it fits on a small section of worktop or a shelf.

What is the correct way to switch between the 15 and 20 degree magnetic angle supports?

Lift the knife off the magnetic base, swap the angle guide to the other side, then place the blade back so the magnets hold it at the new angle.

When should the #400 diamond and #3000 ceramic discs be replaced?

Replace the discs when they no longer raise a burr on the edge or when the ceramic surface feels smooth instead of slightly abrasive.
