Restoring a Chipped Edge – 8 Minutes Total sharpening Time

Repairing a chipped blade removes more material than regular sharpening — we recommend it for occasional restoration only.The actual sharpening and chip repair process took only about 5 minutes. The subsequent use of the 1000 grit, 3000 grit, and dual-sided strop was mainly to refine the micro-serrations and polish the bite of the edge.

Real Results from Real Sharpeners

Don’t just take our word for it — watch how pros and hobbyists alike use it every day
to keep their blades razor sharp.

Real Sharpeners. Real Results.

Veteran sharpener Rramski from the Kitchen Knife Forum tested our system across multiple blades, including a 240mm Sujihiki in AEB-L and an artisan made Gyuto. Using our 1000 and 3000 grit stones and a diamond-loaded leather strop, he achieved a BESS score of 94 in under 10 minutes and even improved that to 72 with further refinement.

He noted the sharpener’s ease of use, consistent angle control, and adaptability across different stone thicknesses. Even VG10 — often tricky to deburr — was handled cleanly thanks to the stable clamp. A chef knife in 52100 tool steel, sharpened from scratch in a kitchen sink setup, reached a BESS score of 116 with minimal effort.

"Leading in diamond stones: 80% abrasive density raises burrs on S90V and Magnacut in seconds — fast, clean, and surprisingly smooth to use."
"Breaks the limits of coarse grinding — powerful, comfortable, and built for high-alloy steels."

When professionals trust it and beginners achieve great results, you know it delivers.

Precision Engineering, From the Ground Up

Every component of this sharpener is designed with a single purpose:
to provide effortless sharpness every time — and built to last for a lifetime.

Diamond Sharpening, Redefined

The included sharpening stone isn’t just durable — it’s engineered for performance and precision. This is a dual-sided 400/1000 grit diamond stone, 4mm thick, made with 100% diamond abrasive using a high-temperature sintering process — not electroplated.

Compared to glass and other ceramics stones , it provides stronger tactile feedback and more friction — allowing better control, especially during fast sharpening.

The core metric we focused on is burr-raising efficiency. In our internal tests on steels like REX121, ZDP-189, and CPM S110V, even under moderately dulled conditions, a stable sharpening stroke could consistently raise a burr in just 5–6 passes.

*Maintaining firm, consistent pressure is key. Let us know how it performs with your blades — we’re eager to hear your results.

4 U-Shaped Bearings + Dual Stainless Steel Shafts

Equipped with four U-shaped stainless steel bearings and dual precision-ground shafts, our base motion system delivers ultra-smooth linear tracking—no wobble, no stutter.
This rock-solid glide ensures consistent sharpening angles and razor-sharp edges, every time.

15-Angle System with ±0.1° Fine Tuning

Choose from 15 positions between 10°–30°,
-perfect for any edged tool from high end kitchen knives to thickest survive beast.The micro-adjust dial offers ±0.1° accuracy, giving you CNC level precision right in your home.

Sink-Mounted Base + Dual-Screw Angle Clamp

Our sharpening platform is engineered to mount securely over most kitchen sinks (inner width: 385–550mm).

Two stainless steel screws firmly lock the angle rail in place.
Paired with a one-piece alloy arm, your sharpening angle remains rock-solid—even after tens of thousands of uses. 

Rigid 4-Point Clamp + Anti-Slip Pads

For use on a flat surface, make sure to tighten all four side-mounted cam screws to lock the base securely. The underside is equipped with anti-slip rubber pads, ideal for countertops and workbenches. If the pads lose grip due to dust or debris, simply wipe them clean with a damp cloth to restore traction.

Lever-Driven 10KG Clamp

A reinforced lever mechanism can stand up to  10KG of weight  — keeping your paring knives, chef’s knives, and gyutos rock-solid while you work.

Symmetrical Flip-Over Clamp

Switch sides under  one second without the need to realign the blade.
The symmetrical clamp keeps the angle on both sides consistent — no guesswork required.

Universal Fit for Knives from 80–300mm

Whether it’s a tiny paring knife  or a 12-inch chef knife, the system adjusts to the length seamlessly.
Ideal for everyday carries, artisan blades, and professional kitchen knives.

Progressive Sharpening Support

Whether you're reviving an old favorite or perfecting a brand-new blade, 
our all-in-one sharpening system takes you from coarse edge to a fine, polished apex.

400 Grit

Chip repair and creating a toothy edge to power through tough cuts like beef. 
Creating a new apex in minutes, making every slice effortless.

1000 Grit

Ideal for fine honing — a refined edge for effortlessly slicing through vegetables and keeps your knife razor-sharp.

Leather Strop

Burr removal, refines the edge, and brings out the blade’s true sharpness.
Achieve a clean, razor-like apex with an edge angle under 60°.

Important Note: After any sharpening progression — 400 grit, 1000 grit, or higher — using the leather strop will remove the excess burr and expose your true razor edge.

Repair Micro-Chips & Damaged Edges

Restoring Chipped Edges Without Compromise
Most sharpeners can make an edge sharper — but frustrates when it comes to repairing chipped edge or fractured steel. 
Our system is here to help: Restoring the damaged edge while preserving the original surface finish.

After repair, the blade profile remains consistent, the surface is free from any scratches, and even Damascus patterns stay perfectly intact. Suitable for high-end knives, from artisan Japanese steel to custom made Damascus knives.

*Note: the front arc of the blade may be ~0.5mm wider after reshaping — a natural result of restoring tip geometry.

Science of Sharpn — What Makes a Sharp Edge?

A truly sharp edge under magnification shows a clean, consistent apex — no cracks, no micro-chipping, no rolling.
Our sharpening system delivers measurable, repeatable results by precisely guiding every stroke.
It's not magic. It's precision engineering backed by real science. 

Compatible with Popular Whetstone Brands

Compatibility with a Wide Range of  Stone Sizes
Our clamp accommodates most popular Stone brands:

Why We Built This

Our family comes from four generations of knife makers.
Sharpness runs in our blood — it’s what we do, what we live.

But even with the sharpest blades at home, we kept asking:
Why is it still so hard to maintain that edge?
Why do good knives go dull so fast?
Why are sharpening tools either clumsy, complicated, or ineffective?

That’s when we realized:
The problem aren’t knives — it’s the sharpening experience.

So we set out to fix it — not just for pros like us,
but for anyone who loves to cook, create, and cut with confidence. 

From First iteration to Functional Prototype

From humble beginnings to engineering refinement — here’s how our sharpening platform evolved.
Every rail, clamp, and joint you see was refined  by feedback, failures, and field testing.

   Gen 1: Angle Shift Flip               Gen 2: One-Second Flip               

   Gen 1: Scratch Marks             Gen 2: Clean Finish      

We tested, failed, and refined — again and again.
From clunky frames to precise modular construction.
From flaky stones to sintered diamonds.
From ideas to innovations that make a real difference.

We did not rush it — because sharpness isn’t just a feature.
It’s an experience.

We Choose Precision Over Speed

In a world chasing fast results, we chose patience.
We are obsessed over angles, feedback, and tactile detail —
not because we’re perfectionists,
but because we believe that every sharp knife brings joy back to cooking.

We didn’t just build a tool — we built a system to restore joy to your kitchen.

Upgrade Kit Performance Preview

The video below showcases an experimental sharpening setup using a 3000-grit prototype stone and a dual-sided leather strop (coarse suede + smooth leather). In our internal slow-cut test, this setup achieved a sharpness score of 47 (BESS) — a level considered “professional-grade” by industry standards.
