Norton 61463686800 Round Sharpening Stone Ultra Fine

Product Description

The NORTON 61463686800 is a round sharpening stone with an ultra fine grade abrasive surface, designed for precision honing and edge refinement on hand tools, cutting instruments, and blades. At 0.25 inches thick, this compact stone is suited for detail work and tight profiles where a larger bench stone would be impractical. It is typically used by machinists, toolmakers, knife sharpeners, and trade professionals who need consistent, fine-grit material removal to polish or refine an already-established edge. The ultra fine grade makes it appropriate for finishing passes rather than heavy stock removal.

This stone is well suited for touchup and finishing work on chisels, gouges, knives, and similar hand tools. Its round shape allows it to reach curved and contoured surfaces that flat stones cannot access, making it a practical addition to a toolbox or field kit. Trades such as plumbing, HVAC sheet metal work, and carpentry may keep a stone like this on hand for maintaining cutting edges on the job.

Compatibility

Designed as a general-purpose honing stone compatible with hand tools, cutting blades, and instruments requiring ultra fine edge refinement.

Installation Notes

Sharpening stones require no installation but should be used on a stable, secure surface to maintain consistent angle and pressure. Follow the tool or blade manufacturer's recommended honing angle for best results. Some stones benefit from a light application of honing oil or water as a lubricant during use — confirm the appropriate lubricant type for this stone before use. Keep the stone clean and store it in a protective case or pouch to prevent chipping.
