Norton 614636-86770 Knife Blade File Sharpening Stone Fine

Product Description

The NORTON 614636-86770 is an India-style knife blade file sharpening stone designed for fine-grade honing of knife edges, file faces, and similar cutting tools. Constructed from aluminum oxide, this triangular cross-section stone measures 1/8 inch thick, 1 inch wide, and 4 inches long, making it well suited for sharpening narrow blades, angled edges, and file teeth where flat stones cannot reach. Sold in cases of 5, this stone is a standard consumable for maintenance shops, tool rooms, and trade professionals who keep cutting tools in working condition.

This sharpening stone is appropriate for use in any trade or maintenance setting where edge tools require regular honing. The fine grade makes it best suited for finish honing after coarser stock removal has already been completed. Electricians, plumbers, HVAC technicians, and general maintenance personnel who rely on sharp utility knives, scoring tools, or trade blades will find this stone a practical addition to a tool kit. The compact size fits easily in a tool bag or service cart drawer.

Key Features

• Fine grade aluminum oxide abrasive for finish honing and edge refinement
• Triangular cross section reaches narrow grooves, file teeth, and angled blade bevels
• Compact 1/8 x 1 x 4 inch profile fits tight workspaces and small blade geometries
• India-style construction provides consistent abrasive density across the stone face
• Case quantity of 5 supports ongoing shop or fleet maintenance supply needs

Compatibility

Designed as a general-purpose fine sharpening stone suitable for knife blades, file faces, and similar narrow cutting tools requiring a triangular abrasive profile.

Installation Notes

A licensed tradesperson or experienced maintenance technician should secure the workpiece or stone firmly before honing to prevent slipping and injury. Light honing oil or water is typically applied to the stone surface to float swarf and extend stone life. Maintain consistent angle contact between the blade and stone face throughout each stroke. Keep the stone clean and stored dry when not in use to prevent contamination of the abrasive surface.
