hiomakivet

Hiomakivet, or sharpening stones, are tools used to create and maintain a sharp edge on metal blades and other edged implements. They are employed by woodworkers, chefs, hobbyists, and metalworkers to remove micro‑roughness and to hone the blade’s edge through controlled abrasion.

Hiomakivet come in natural and synthetic forms. Natural whetstones occur in various deposits and differ in hardness, porosity, and grain structure. Synthetic whetstones are manufactured from abrasive materials such as silicon carbide or aluminum oxide and are produced in a wide range of grits. Grit size determines the level of material removal and the smoothness of the final edge.

The grit progression typically starts with coarse grits for repairing or reshaping dull edges, moves to medium grits for sharpening, and ends with fine or extra-fine grits for honing and polishing. Some stones are optimized for use with water, others with honing oil, depending on their composition and recommended practice.

Preparation and technique involve properly lubricating the stone and maintaining a consistent edge angle while rubbing the blade across the surface. Regular maintenance includes cleaning away slurry and debris and flattening or re-lapping the stone when its surface becomes uneven or glazed, to preserve flatness and performance.

Care and storage considerations help extend the stone’s life. Natural stones may require drying and gentle handling to prevent cracking, while synthetic stones should be kept clean and dry after use. Hiomakivet provide a simple, versatile means of sharpening a wide range of edged tools.
