Iki Ruixin Sharpener

Not at all. The clamp-based design locks your blade in place and maintains a consistent angle, which removes the need for the steady hand and muscle memory required by traditional freehand stone sharpening.

The system is designed primarily for straight-edged blades like kitchen knives, pocket knives, and woodworking tools. While it can handle scissors, it is not suitable for serrated edges, which require specialized sharpening tools.

This unit uses a table clamp rather than a non-slip base. You will need a sturdy table or countertop edge to securely mount the sharpener before you begin your work.

The four stones allow you to progress from heavy repair to a polished edge. You start with the #120 grit for removing nicks or reshaping a dull edge, move through the #320 and #600 for refining, and finish with the #1500 grit to hone the blade to a razor-sharp polish.

Yes, the adjustable clamp system allows you to set the angle anywhere between 10 and 50 degrees. This flexibility lets you match the specific factory bevel of your knife or customize the edge geometry for different tasks, such as a thinner angle for slicing or a wider angle for heavy-duty work.

Because the unit is made from aluminum alloy and stainless steel, it is very durable. Simply wipe the metal components down with a dry cloth after use to remove metal shavings; note that the unit is not dishwasher safe.
