The 25 pages that link to Hardness, each with the reason it gives.

• Ionic bondingRelated: Strong crystal cohesion makes many ionic solids hard, though their planes can cleave.

• Food textureRelated: It captures the force needed to bite or press a food.

• CuttingRelated: A tool generally needs sufficient hardness to penetrate the material without blunting.

• CementiteRelated: Cementite’s high hardness raises the hardness of carbide-containing structures.

• SharpeningRelated: Hardness influences how readily abrasive particles remove blade material.

• BladeRelated: Blade hardness helps resist edge deformation but does not by itself ensure toughness.

• Knife edgeRelated: Hardness helps an edge resist deformation during cutting.

• Chromium platingRelated: Hard chromium can resist surface damage and abrasive wear.

• Knife bladeRelated: Blade hardness affects edge retention and the risk of chipping.

• Tool (implement)Related: Working edges need sufficient hardness to resist wear and deformation.

• SodaliteRelated: Sodalite’s hardness helps determine suitable cutting, polishing, and jewelry settings.

• ArmourRelated: Hard surfaces can blunt or fracture penetrators, though hardness alone does not guarantee protection.

• Tantalum carbideRelated: High hardness lets tantalum carbide resist abrasion and cut other materials.

• AllotropeRelated: Diamond’s network structure makes it far harder than graphite, despite both being carbon.

• Armor-piercing bulletRelated: Core hardness helps determine whether the projectile deforms on impact.

• Titanium nitrideRelated: TiN’s high hardness helps its coatings resist scratching and abrasive wear.
