Edge & Oak Diamond Replacement Disc

R 349.99

Different grit ratings correspond to specific stages of edge maintenance, ranging from heavy repair to high-precision polishing. Choosing the correct disc depends on the current condition of the blade and the intended final finish:

The Edge & Oak Diamond Discs — Repair → Sharpen → Refine → Polish → Mirror

240 Grit — Repair & Reshape (Extra Coarse): For serious edge damage. Resets deep nicks, removes chips, and brings a neglected or badly dull blade back to life. The heavy lifter of the set.
400 Grit — Sharpen (Coarse): Builds a fresh cutting edge on a dull knife. Removes metal efficiently to set a clean bevel before you move to the finer discs.
1000 Grit — Refine (Fine): Your everyday sharp. Smooths the edge for clean, effortless slicing — perfect for routine kitchen prep and caring for good steel.
1500 Grit — Polish (Extra Fine): Removes the last micro-scratches and finishes the edge to a razor, near-mirror sharpness. The touch that separates "sharp" from "scary sharp."
3000 Grit — Mirror Finish (Ultra Fine): For high-end and Japanese knives. Takes an already-sharp edge to a flawless mirror polish — ideal for delicate work like carving, filleting and sashimi, and for enthusiasts who want the finest edge possible.

Will these spare discs fit my Edge & Oak rolling sharpener, and are they easy to swap out?

Yes, absolutely. Every individual grit disc features our mounting system, designed to fit seamlessly onto your existing Edge & Oak roller. Swapping discs takes less than five seconds... simply unscrew the current disc and screw the new one into place. No tools, no technical skills, and zero hassle required.

Which grit size do I actually need for my knives right now?

It depends on the current state of your blades:

240 & 400 Grit (Coarse): Best if your blade is severely dull, chipped, nicked, or needs a complete edge reset.
1000 & 1500 Grit (Medium-Fine): Ideal for regular, monthly maintenance to bring a clean, razor-sharp cutting edge back to everyday knives.
3000 Grit (Ultra-Fine Polish): Designed for food enthusiasts wanting a mirror-like, hair-splitting edge for delicate tasks like slicing sashimi or paper-thin tomatoes.

Are these genuine industrial-grade surfaces, or will the grit rub off after a few uses?

We don't use cheap painted coatings that flake off into metal dust. Our 240 to 1500 discs use high-density electroplated industrial diamond particles, while our 3000 grit features a solid, ultra-fine ceramic matrix. They are engineered for exceptional durability, tested to withstand years of regular sharpening without losing their abrasive integrity.

Release with a gentle twist.

Align your desired grit.

Secure and begin.

We want you to feel 100% confident testing Edge & Oak on your own cutting board. If you try our rolling sharpener and don't feel it delivers effortless, razor-sharp results to your everyday kitchen knives, we will gladly refund your purchase price within 30 days of delivery.

FAQ'S

Everything You're Wondering

Do I need to buy all five grit sizes, or can I just buy one?

You can buy individual discs based on your specific needs! If you just need to maintain already sharp knives, a single 1000 or 1500 grit disc is perfect. However, if you have a mix of damaged blades and high-end cutlery, building a progression set allows you to take steel from rough repair (240 grit) all the way to a high-end, mirror-polish finish (3000 grit).

Is the 3000 grit ceramic disc too delicate or easy to break?

Not at all. While 3000 grit ceramic is a refined, ultra-fine finishing material, it is housed in a durable steel backing plate. As long as it is stored properly in a drawer or case and not dropped onto hard tile flooring, it will deliver thousands of mirror-polish passes without cracking or degrading.

Can using the wrong grit permanently damage my expensive knives?

No, because the angle is safely locked in by your Edge & Oak magnetic base. The only rule of thumb is speed: coarse grits (240/400) remove metal faster to fix damage, so they only need a few passes. Fine grits (1500/3000) remove micro-fractions of steel, making them virtually impossible to "over-sharpen" or ruin your cutlery.

How do I clean fine steel dust out of the finer grits (1500 & 3000)?

Over time, microscopic steel particles can collect in the fine pores of the ceramic and diamond surfaces. Cleaning them is effortless: simply wipe the disc with a damp microfiber cloth or scrub it gently with a dry soft-bristle toothbrush to lift the steel dust and restore 100% of its sharpening bite.

If I order today, what is the exact delivery timeline to my door?

To give you complete peace of mind, we quote a 2-week delivery window at checkout. Please note that this is an exaggerated buffer to account for high demand and potential courier delays—most local orders arrive much faster! Once you place your order:

We take up to 3 business days to pack and inspect your individual discs.
As soon as our door-to-door courier picks up your package, you receive an SMS and email with live tracking so you can follow your order right to your doorstep.

What if I order the wrong grit size by mistake?

We want your purchase to be completely risk-free. If you open your package and realize you ordered a 240 grit instead of a 1000 grit (or vice versa), simply contact our local South African support team within 30 days. As long as the disc is unused, we will gladly arrange an easy exchange for the exact grit you need.

Ordered the 240 and 1500 grit discs to fix up my daily kitchen knives. Changing them on the roller takes literally 5 seconds. My knives are slicing through tomatoes like butter again. Arrived in Jhb in 3 days, very happy with the quality.

Skeptical at first because cheap sharpeners usually destroy your blades, but these discs are top tier. The 3000 grit ceramic gives an incredible mirror polish which is just what i was looking for as I have High End knives!

Does exactly what it says. Used the 240 grit to reset an old dull blade, then moved to 1000. It glides effortlessly now. Delivery was quick to CPT.
