Sharpening a chef's knife at 20 degrees with the Oakstone rolling sharpener

The problem

Every knife goes blunt. Most sharpeners make it worse.

A blunt knife slips, squashes tomatoes and turns prep into a fight. Pull-through sharpeners tear steel off the edge. Whetstones take years to learn. So most good knives end up blunt in a drawer.

Oakstone takes the skill out of it. The magnets hold the angle. You just roll.

    1. Set the angle

    Place the knife on the magnetic base. 15° for fine Japanese blades, 20° for European chef's knives. The magnets hold it there, so the angle never drifts.

    Roll the 400 grit diamond disc along the blade to grind a fresh edge. Flip to the 1000 grit ceramic disc to hone it clean.

Grind

400 grit industrial diamond

Diamond is harder than any knife steel, so it cuts a clean new edge on soft German steel and hard Japanese and Damascus blades alike. It grinds the steel instead of tearing it like a pull-through sharpener.

Hone

1000 grit ceramic

Grinding leaves a tiny burr of loose steel on the edge. The ceramic disc removes it and polishes the edge smooth, which is the step that makes a knife feel truly sharp.

Hold

Solid oak and N50 magnets

Triple-layered N50 magnets lock the blade at 15° or 20°, so every pass hits the same angle. Oak and stainless steel with no plastic in the rolling system. It lives on the bench, not in a drawer.

  • “Really impressed with the Oakstone knife sharpener! Excellent build quality, very easy to use and does exactly what it’s supposed to. Brought my knives back to razor sharp with very little effort. I looked at quite a few different sharpeners before choosing this one and I’m glad I did. Great quality product and definitely worth the money. Highly recommend!”

  • “Such an incredible knife sharpener! Very useful instructions provided, easy to use and I couldn’t believe how sharp my knives were when I did it. If you’re a chef or enjoy doing bbq (especially Brazilian style haha), I would definitely recommend this tool… I bet you won’t regret it once you cut a nice picanha with a clean and precise cut, without tearing the meat…
    Simply loved it! 😄”

Meet the founders

We built the sharpener we wanted at our own BBQ

We are two Brazilians who moved to Adelaide over a decade ago and found the Aussie BBQ felt just like home. The prep did not. Every weekend we fought blunt knives, and sharpening felt like a mystery. After burning through cheap sharpeners, we designed one that holds the angle for you. That became Oakstone.

Before you buy

Questions, answered

How does the Oakstone sharpener work?

Set the knife on the magnetic base at 15° or 20°. Roll the diamond disc along the edge to grind a fresh bevel, flip the knife and repeat, then finish with the ceramic disc to hone it. The magnets hold the angle, so there is no technique to learn.

15° or 20°: which angle do I need?

  • 15°: a finer, sharper edge for Japanese-style knives, carbon steel and precision slicing.
  • 20°: a tougher edge for European chef's knives and heavy chopping.

Not sure? Most Western chef's knives are 20°. Our angle guide explains how to tell.

What do the diamond and ceramic discs do?

  • 400 grit diamond: grinds a new edge on blunt blades, including hard steels and Damascus.
  • 1000 grit ceramic: removes the burr and polishes the edge clean.

Which knives can I sharpen?

Any smooth-edged steel blade: chef's knives, santokus, paring knives, cleavers, pocket, hunting, fishing and camping knives.

Not suitable: serrated blades such as bread knives, ceramic knives and scissors.

How often should I sharpen?

When the knife stops slicing cleanly through a tomato skin. A few passes on the ceramic disc between full sharpens keeps the edge in shape for longer.

How fast is shipping, and what does it cost?

Shipping is free Australia-wide. We pack every order in Adelaide within 1 to 2 business days, and Australia Post delivers in 5 to 8 business days. You get tracking by email.

What if I change my mind?

Return it unused, in its original packaging, within 30 days of delivery. You cover return postage for change of mind. If anything is faulty, we cover it, as the Australian Consumer Law requires. See our refund policy.
