## Overview

The Norton Crystolon Abrasive Machine Knife Stone is a dual-grit silicon carbide sharpening stone (100 coarse / 280 fine) designed for efficient edge repair and honing of machine knives and cutting tools. Its 4" diameter and 1.5" thickness provide a compact, ergonomic grip enhanced by a protective groove, making it ideal for professional use in machine shops, paper, and cloth-cutting environments. Durable and versatile, it delivers fast sharpening and smooth finishes, ensuring your blades stay precision-sharp and ready for action.

## Description

Built for use in paper and cloth-cutting shops, the Norton Crystolon Machine Knife Stone sharpens and hones with ease. Made with a dual grit silicon carbide abrasive, use the coarse grit side for sharpening and the fine side for honing paper and cloth-cutting knives and planer knives. For maximum comfort and usability, these stones feature a groove around the middle to protect fingers and provide a secure hold.

Review: Great for a machine shop - This is exactly what I needed for cleaning up the surface of my milling machines. The stone has dual grit, which isn't really that useful, but I suppose the rough side could be used for larger burrs and oopsies on the mill. The fine side is perfect for finding and smoothing down the mill table. It's also useful for cleaning up the bottom of Kurt vices and any other part of a machine tool that should be flat.
Review: Blanchard surface stone. - Perfect for work on grinding tables. Removes burrs and high spots with coarse or smooth surfaces. Works best on Blanchard magnetic table surfaces. Long lasting as well. Fits in your hand with ease.

## Features

- Combination oilstone has 100 grit on one face for repairing cutting edges and 280 grit on the opposite face for sharpening and maintaining them
- Silicon carbide sharpens to moderate tolerances when it is more important to sharpen the blade quickly than to produce a fine cutting edge
- Disk-shaped for hand sharpening of machine knives and garden or household cutting tools
- Groove around circumference of stone for secure hold and protection of fingers
- Compact for easy portability
