FAQs
How is the Diamond Coarse disc different from Diamond Standard?
The Coarse disc uses a larger diamond grit and removes steel more quickly. The Standard disc is the general-purpose choice for normal sharpening.
When should I use the Coarse disc?
Use it when a knife is very blunt, has slight edge damage, or needs enough material removed to establish a different sharpening angle.
Should I finish sharpening with the Coarse disc?
The Coarse disc is intended for heavier material removal. Follow it with the appropriate finer sharpening and honing stages to refine the edge.
Can I use it to change a knife from one edge angle to another?
Yes. HORL specifically recommends the Coarse disc for faster grinding when changing an existing sharpening angle.
Does it fit the HORL 3 Cruise?
No. The HORL 3 Cruise has permanently fitted discs and does not use the Quick Lock accessory system.
Use & Care
- Use for very blunt blades, minor edge damage, or significant angle changes
- Switch to a finer HORL disc once the required edge geometry has been established
- A small amount of excess diamond material may release during the first use
- The surface reaches its intended working roughness after the initial break-in period
- Use HORL Quick Lock to remove or install the disc
- Keep the disc free of accumulated grinding residue when stored

HORL 3 Diamond Grinding Disc, Coarse
The HORL 3 Diamond Coarse Grinding Disc is the faster-cutting option for knives that need more correction than routine sharpening. Its larger diamond grit removes steel more aggressively than the Diamond Standard disc, making it useful for very blunt edges, slightly damaged blades, and situations where you need to change an existing sharpening angle.
Sharpening sequence
Where it fits
Follow the HORL sharpening sequence from faster material removal through fine polishing and final leather finishing.
