The global knife sharpener market is projected at USD 902.69 million in 2025 and is expected to reach USD 1,301.65 million by 2033, growing at a 4.68% CAGR. The manual sharpener segment — which includes rolling sharpeners — is expanding faster than electric models, driven by home cooks who want a sharp knife without the mess of a whetstone or the destructive power of an electric grinder.
