Designed for Precision. Built to Last.
Unlike sharpeners designed to be decorative or disposable, this tool is built with performance in mind. From its solid hardwood body to its fixed precision angles and magnetic blade control, every detail exists to deliver consistent, repeatable sharpness — day after day.
BUILT FROM SOLID HARDWOOD
Our sharpening guides are made using responsibly sourced solid hardwood, selected for both performance and longevity. By working with durable natural materials, we create a product designed to reduce waste through long-term use — not replacement.
DIAMOND DISC FOR FAST EDGE RESTORATION
The diamond disc features lab-grown industrial diamonds (Mohs 10), engineered for fast, consistent steel removal. Permanently bonded to the surface, the diamond abrasive delivers durable performance and reliable sharpening results, a method trusted in sharpening tools for decades.
STAINLESS STEEL HONING DISC
Once the blade is sharpened, the stainless steel disc smooths the edge for a cleaner finish. It removes fine grinding residue and helps the edge feel sharper, more controlled, and ready for everyday use — all in just a few strokes.
15° ANGLE FOR FINE EDGE PERFORMANCE
The 15° grinding angle creates a finer, more precise cutting edge. It’s ideal for high-quality blades that prioritise sharpness and clean slicing, delivering exceptional cutting performance with minimal resistance.
20° ANGLE FOR STRONG, EVERYDAY EDGES
The 20° grinding angle is designed to create a strong, long-lasting edge suited for everyday use. It balances sharpness with durability, making it ideal for chef’s knives and other blades that see regular, heavier cutting.
“Clean, consistent sharpness every time.”

FAQ's
How long does the diamond disc last?
How long does the diamond disc last?
The diamond disc is designed to last for years with normal home use. It uses industrial-grade, lab-grown diamond abrasive, which wears extremely slowly compared to ceramic or steel. For most users, it won’t need replacing under typical sharpening routines.
Why use this instead of a whetstone?
Why use this instead of a whetstone?
Whetstones require practice, pressure control, and holding a consistent angle. This system fixes the angle for you, so you get repeatable results without the learning curve. It’s faster, cleaner, and far more consistent for everyday home sharpening.
What types of knives does this work on?
What types of knives does this work on?
It’s designed for most straight-edge kitchen knives, including chef’s knives, santokus, utility knives, and similar everyday blades. It’s suitable for both Western and Japanese-style knives. It’s not intended for serrated knives, scissors, or specialty blades that require dedicated sharpening tools.
How often should I use it?
How often should I use it?
For most home kitchens, light sharpening every 2–4 weeks is enough to keep knives performing well. If you cook frequently, you may use it more often for quick touch-ups rather than waiting until knives feel dull.
