Value Collection U313A Oval Tapered Sharpening Stone 220 Grit

Product Description

The VALUE COLLECTION U313A is an oval tapered sharpening stone designed for precision honing of narrow grooves, serrations, gouges, and curved tool edges. Made from aluminum oxide and pre-filled with oil, it delivers medium-grade cutting action at 220 grit, making it well suited for restoring edges that have lost sharpness without removing excessive material. The tapered profile narrows from a larger end to a fine tip, allowing access to tight angles and contoured surfaces that flat stones cannot reach. Machinists, woodworkers, knife sharpeners, and tool-and-die trades keep this style of stone on hand for detailed honing work.

This stone is used wherever a tapered or pointed contact surface is needed to sharpen or deburr. Common applications include honing the flutes of carving gouges, touching up serrated blades, cleaning up gapped or nicked saw teeth, and dressing the inside radii of cutting tools. The oval tapered form is a standard shape in bench sharpening kits and touch-up pouches carried by field service technicians and craftspeople who maintain edge tools regularly.

Key Features

• Oval tapered profile allows access to grooves, serrations, and curved edges
• 220 grit medium grade removes material efficiently while leaving a clean edge
• Aluminum oxide abrasive provides consistent, durable cutting action
• Oil-filled construction lubricates the surface during use to reduce loading
• Tapers from 3/16 inch wide at the small end to 1/2 inch wide at the large end
• Lightweight at 0.08 pounds, easy to carry in a tool roll or kit pouch

Compatibility

Designed as a general-purpose oval tapered sharpening stone suitable for use on carbon steel and tool steel edges in hand tools, cutting tools, and similar bladed implements.

Installation Notes

Apply a light coat of honing oil to the stone surface before use to prevent swarf from clogging the abrasive. Hold the stone firmly or secure the workpiece, then work the stone in smooth, controlled strokes along the edge profile. Clean the stone after use with a cloth and additional oil to remove embedded metal particles and maintain cutting efficiency. No power tools or mechanical fixtures are required for hand honing with this stone.
