A QUICK CHECK

Your knife is definitely dull if…

…it squashes the tomato

You press down, the skin gives all at once, and the slice is a mess.

…it slides off the onion

A sharp knife bites where you put it. A dull one skates across the skin.

…you saw at the meat

Three passes where one should do it.

…you force it through

You lean on the knife to get through produce. One slip is a trip to the medical center.
WHAT IT'S ALREADY COSTING YOU

A dull knife robs you of time and safety

A blade held against a grinding wheel, sparks coming off the edge

The edge you grind away is gone

A one-angle sharpener puts a coarse edge on a fine knife. Do that enough times and the knife is finished.

The new set you didn't need

Most knives get replaced long before they are worn out. A dull knife and a dead knife feel the same in your hand.

A dull knife slips

It needs more force to cut. More force is how your hand ends up in front of the blade.

WHY IT DOESN'T WRECK YOUR KNIFE

Tungsten clears the burr. Ceramic polishes the edge.

A dull edge carries a burr. That is a thin curl of rolled metal along the cutting edge, and it is what stops the knife biting.

TUNGSTEN
Takes the burr off a dull edge. It follows the bevel your knife already has.
CERAMIC
Polishes what is underneath, so the edge comes up clean and holds longer.
YOUR ANGLE
You set it before the knife goes in. Both stages follow that setting on every pull.
The three slots on the Orange Ninja, labelled coarse, medium and fine, beside the angle adjust dial

A cheap pull-through cannot do this. It has one slot, fixed at one angle. If your knife was ground at 15° and the slot sits at 20°, the only way it can reach the edge is to grind the shoulder off the blade. That is why a good knife never quite comes back after a few passes through one.

HOW IT WORKS

Set the angle. Pull it through. Done.

  1. 1COARSERepairs a chipped or rolled edge. Skip it if the knife is only a little dull.
  2. 2MEDIUMSharpens. A few light pulls at the angle you set.
  3. 3FINEPolishes the edge smooth and takes the burr off.

Pull only. Draw the knife toward you from heel to tip. Never push it back through.

WILL IT DO MY KNIVES?

Five angles. Every knife.

Turn the knob until the arrow lines up. The angle holds for every pull.

Not sure? Set it to 18°. That suits most kitchen knives. Go down a step if the blade is thin. Straight edges only — serrated knives won't work in it.

This is probably the easiest and fastest I've ever made my knives razor sharp. I have used other manual knife sharpeners and this is by far absolutely the best I have ever used. I even tried the scissor sharpener and OMG my cheap kitchen scissors became razor blades.

I've used cleaver on tons of rib tips over last twenty years cooking for fund raising for our church it cuts like new again!!! Plus all my knives are sharpened now.

I always sharpened my own knives on a steel rod. I thought it was good enough until I tried the Orange Ninja. Tomatoes slice like butter. It is sturdy, it does not slip, and you do not need to put pressure on it.

I've utilized this on every knife I own, including those of lower quality, and it has been fantastic.

BEFORE YOU CLOSE THE TAB

Straight answers.

Which angle do I use?

Set it to 18° for most kitchen knives. Use 12° for fillet and sushi knives, 15° for Asian knives, 21° for outdoor knives and 24° for hunting and pocket knives. The chart above has the lot.

Will it grind my knife away?

No. The tungsten clears the burr off the edge. It does not take the knife with it. If the blade is only a little dull, start in the fine slot and skip the coarse one.

Does it work on serrated knives?

No. Straight edges only. Bread knives and steak knives with teeth will not sharpen in it.

How long does one knife take?

About two minutes. A few light pulls through each slot you need.

Does it sharpen scissors?

Not this one. The 4-in-1 scissor sharpener does, and it comes in the bundle above. It has four angles for kitchen, fabric, hair and craft scissors.

What does shipping cost, and when will it get here?

Shipping is worked out at checkout. Orders ship from our U.S. warehouse and take 3 to 7 business days.

What if I don't get on with it?

Send it back within 30 days and get your money back. No questions asked.
