This disk-shaped hand oilstone is\r\ncommonly used to restore cutting edges on paper- and cloth-cutting knives and\r\nplaner knives while they are on the machine; it can also be a preferred stone\r\nfor garden and household tools. A groove around the circumference of the stone\r\noffers a secure hold and protection for fingers. Its compactness makes it\r\neasily portable. This silicon carbide stone must be lubricated with oil before\r\nuse, to prevent metal from bonding with the abrasive surface of the stone. The\r\nstone is fast-cutting and offers effective sharpening even under light\r\npressure. It is created by grading silicon carbide to a consistent particle\r\nsize and blending it with bonding agents. It is then molded and surface-\r\nfinished. This knife stone is 1-1\/2 inches high and 4 inches in diameter,\r\nsuitable for hand use. It conforms to the American National Standards\r\nInstitute (ANSI) abrasive grit standard.Sharpening stones, or whetstones, are\r\nabrasive surfaces used to sharpen and hone the edges of steel cutting\r\nimplements, such as chisels, knives, scissors, hand scrapers, and plane\r\nblades. Sharpening is the process of creating or re-establishing a cutting\r\nedge by grinding away portions of the metal to adjust the angle of the edge\r\nand reform the shape. Honing removes small imperfections. Stones can be flat,\r\nfor working flat edges, or shaped, for edges that are more complex. Sharpening\r\nstones are made of natural or synthetic materials that range from softer to\r\nharder, and are categorized by the size of their abrasive particles, known as\r\ngrit. A stone with a coarser grit is used when more metal needs to be removed\r\n(e.g., when sharpening a nicked or very dull blade); the stone with the finest\r\ngrit produces the sharpest edge. Where numbers are assigned to specify grit,\r\nthey range from coarser grit (low) to finer grit (high). Some sharpening\r\nstones are designed for use with a lubricating liquid, some can be used dry,\r\nand others can be used either wet or dry. When used with lubricating liquid, a\r\nsharpening stone can be called a waterstone or an oilstone, based on the\r\nlubricant required.Norton Abrasives manufactures sanding, grinding, and\r\npolishing abrasives, and has been located in the United States since 1885.\r\nNorton, now a brand of Saint-Gobain, meets ISO 9000 and 14001 certification\r\nfor quality and environmental management standards.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n \u003cul class=\"a\"\u003e\r\n \u003cli\u003eCombination oilstone has 100 grit on one face for repairing cutting edges and 280 grit on the opposite face for sharpening and maintaining them\u003c\/li\u003e\r\n \u003cli\u003eSilicon carbide sharpens to moderate tolerances when it is more important to sharpen the blade quickly than to produce a fine cutting edge\u003c\/li\u003e\r\n \u003cli\u003eDisk-shaped for hand sharpening of machine knives and garden or household cutting tools\u003c\/li\u003e\r\n \u003cli\u003eGroove around circumference of stone for secure hold and protection of fingers\u003c\/li\u003e\r\n \u003cli\u003eCompact for easy portability\u003c\/li\u003e\r\n \u003c\/ul\u003e","published_at":"2025-10-30T05:28:09+11:00","created_at":"2025-10-30T05:28:05+11:00","vendor":"Norton","type":"Sharpening Stones","tags":["home_selected_Nov2025"],"price":29300,"price_min":29300,"price_max":29300,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":48943952429293,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B000RU8TQA","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Norton Crystolon Abrasive Machine Knife Stone, Silicon Carbide, 4\" Diameter x 1-1\/2\" Thickness, Grit Coarse\/Fine (Pack of 1)","public_title":null,"options":["Default Title"],"price":29300,"weight":531,"compare_at_price":null,"inventory_management":"shopify","barcode":"614636875705","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/leoforward.com\/cdn\/shop\/files\/B000RU8TQA.jpg?v=1775801299","\/\/leoforward.com\/cdn\/shop\/files\/91vnqCkz5DL.jpg?v=1761762489","\/\/leoforward.com\/cdn\/shop\/files\/917qtiY9HWL.jpg?v=1761762488","\/\/leoforward.com\/cdn\/shop\/files\/91Xo_b7Cx6L.jpg?v=1761762489"],"featured_image":"\/\/leoforward.com\/cdn\/shop\/files\/B000RU8TQA.jpg?v=1775801299","options":["Title"],"media":[{"alt":null,"id":37029609111789,"position":1,"preview_image":{"aspect_ratio":1.0,"height":1000,"width":1000,"src":"\/\/leoforward.com\/cdn\/shop\/files\/B000RU8TQA.jpg?v=1775801299"},"aspect_ratio":1.0,"height":1000,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/B000RU8TQA.jpg?v=1775801299","width":1000},{"alt":null,"id":37029609144557,"position":2,"preview_image":{"aspect_ratio":1.0,"height":2560,"width":2560,"src":"\/\/leoforward.com\/cdn\/shop\/files\/91vnqCkz5DL.jpg?v=1761762489"},"aspect_ratio":1.0,"height":2560,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/91vnqCkz5DL.jpg?v=1761762489","width":2560},{"alt":null,"id":37029609177325,"position":3,"preview_image":{"aspect_ratio":1.0,"height":2560,"width":2560,"src":"\/\/leoforward.com\/cdn\/shop\/files\/917qtiY9HWL.jpg?v=1761762488"},"aspect_ratio":1.0,"height":2560,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/917qtiY9HWL.jpg?v=1761762488","width":2560},{"alt":null,"id":37029609210093,"position":4,"preview_image":{"aspect_ratio":1.0,"height":2560,"width":2560,"src":"\/\/leoforward.com\/cdn\/shop\/files\/91Xo_b7Cx6L.jpg?v=1761762489"},"aspect_ratio":1.0,"height":2560,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/91Xo_b7Cx6L.jpg?v=1761762489","width":2560}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eNorton Crystolon Abrasive Machine Knife Stone, Silicon Carbide, 4\" Diameter x 1-1\/2\" Thickness, Grit Coarse\/Fine (Pack of 1)\u003c\/h3\u003e\r\n\u003cp id=\"b\"\u003eThe Norton Crystolon 100\/280-grit combination abrasive machine knife stone is\r\nmade of silicon carbide with 100 grit on one face for repairing cutting edges\r\nand 280 grit on the opposite face for sharpening and maintaining them; it\r\nsharpens to moderate tolerances when it is more important to sharpen the blade\r\nquickly than to produce a fine cutting edge.
