The Olurrisa 4-in-1 is a manual pull-through sharpener with four slots: diamond for repairing and straightening damaged edges, tungsten steel for restoring a V edge, ceramic stone for honing and polishing, and a ceramic slot for scissors. It is a compact, hand-held tool with an ergonomic handle and a rubber hanging ring, so it stores easily and needs no power. It suits home cooks who want a quick tune-up on kitchen knives and household scissors without learning whetstone technique. Against electric sharpeners it is simpler and quieter but removes metal fast in the coarse slots and gives less control than a stone or guided system.

This is a 4-in-1 sharpener for kitchen knives and scissors. It has four slots, each for a different step: preparing, fine-tuning, sharpening and scissor sharpening. It has an ergonomic handle and a rubber hanging ring.
Slot 1 has a diamond surface that repairs and straightens damaged metal blades. Slot 2 has a ceramic stone that polishes the blade and evens out surface irregularities, including those left by sharpening. Slot 3 has tungsten steel that restores the cutting edge to a V shape. Slot 4 has a ceramic slot for sharpening scissor blades.
For a slightly dull knife, pull it through the diamond slot 5 times. For a moderately dull knife, use the ceramic slot 5 times, then the diamond slot 5 times. For a severely dull knife, use the tungsten steel slot 5 times, then the ceramic slot 5 times, then the diamond slot 5 times. Sharpen only clean, dry blades. Pull the blade in one direction only, not back and forth, and make at least five passes per slot.
