How to use the Tumbler Diamond Rolling Knife Sharpener

will not work on small pocket knives only large kitchen

These instructions must be wrong. it makes no sense to horn the same side before sharpening the other side. The way it shows the video, you're going go create a burr on the opposite side. You have to go back and horn.the original side once you've sharpen the other side.

How much is it

If you have very dull knife sharpen 5-8 minutes each side ? I have been doing like 50 strokes per side . Getting some results

Just got a tumbler for Christmas. Highly disappointed! Not as advertised! Does not sharpen as advertised. 1 out of 10!

When I bought this several years ago I didn't realize that the center is stationary, mine moves with the plates and is kind of a pain to use. And having now looked into more reviews, this seems to be a common problem with Tumbler.

its funny how the first slice didnt cut the tomato skin at the bottom then it zoomed in to not show it. like you cant reshoot it? only got 1 tomato or what lol

My Tumbler doesn't spin like that, I have to roll it...

damn my diamond disk doesn't roll. it's stiff

What is considered a specialty knife? Examples?

Should have cleaned your nails before taking the last shots. Gross. (good video otherwise!)

What about for knives of different heights.

Does it take 5-6 minutes to sharpen each side or is it 5-6 minutes in total?

Question. Is there an easier way to get the roller to move more freely? Mine seems to be very tight and doesn’t spin easily?? Thanks.

Out of curiosity, I got one recently. How much pressure should one be applying towards the blade with the sharpener. I haven't been getting the best results (not bad), and I'm curious as to how much pressure is being applied to the blade.

yes it works - BUT don't do this on a granite or marble surface - the rolling part actually scared the surface of my granite counter top!!! there should be a warning on this - do it on a cutting board and you'll be happier....wonder if Tumblr will pay for someone to come to the house and resurface my granite??!!

This shit is 8 dollars on AliExpress lol

your product is a cheap and easily exhaustible copy of a really good product by a german manufacturer, it's sad you have 1m subs

Thanks

Looks like the center piece rolls separate from the ends. Just learned that that’s how it is supposed to work, was wondering why it didn’t work very well. I have had mine for a few months now and to get the ends to roll separate from the middle takes a lot of force and makes it hard to sharpen. Anything that can be done to fix this like adding oil somewhere?

How can I get this but it can’t ship to Australia

Good vid showing how it works, wouldn’t mind seeing some of the actual sound come through… is it supposed to sound like shrieking metal, chopping and grinding, a faint humming buzz? Lets us know how much pressure to use!

My Tumbler stiffened up and barely turns. I have to squeeze it to the counter with all my might. Can it be lubricated or loosened?

Okay I can’t help but point out that there is a high risk of slipping if you don’t include like a silicone grip on the actual cylinder.
Factor is just as important as form.
Knock it off with the pushy marketing, and worry about refining your product first.

Be easy to 3d print and add sand paper as the abrasive

Too expensive. Hope they go bankrupt figuring that out.

I love the easy instructions and the product is top notch. Only, I’m laser focused on this hand actor having poor knife skills with his fingers sticking straight out on that Mater, but worse than that is the nail hygiene….ooooof. Bro. BRO! No no no no no no.

Almost made it through the tomato without sawing.

I wish the magnet was stronger. I also find with mine that it seems to be really really stiff to roll… also the O Rings will leave marks on most counter tops that are a pain to clean. Maybe that’s just because mine is so stiff to roll you need so much downward pressure to stop it just sliding on the counter.

Can you make another video explaining the science behind the two different sides. Like I get the idea of creating the burr but I thought the burr was removed when you started shaving the other side. Is it the honing that removed the burr you create?

Try and use this with a knife that is narrower than the stand……..good luck !

Ain’t worth a dime. I wasted over $100 on this stupid thing just to dull my knives. Don’t waste your money.

Perhaps this is a dumb question, but how can the holder possibly hold a knife in place while you grind its edge? I understand that it's a magnet, but I'm familiar with magnets and can't picture one being strong enough to secure a knife while you're sharpening it. Or.. does it take five minutes because you need to rub it softly? Is that the idea-- don't put much force on it so the magnet sticks?

Fairly useless on narrow knifes

I’m a butcher for Winn Dixie and NEED a very sharp knife for big primal cuts. Will this work
This video got him cutting a tomato. I need it to cut thru big chuck rst top round rst with ease

Do not pay for this overpriced nonsense.

Lol. No. One side is primary bevel, Other side is secondary bevel.

This is a below average good knife sharpener, it will take you a long time to roll an edge. 🤷🏼

How we can get it

It’s just not available in India?”

This sharpen is worthless for folding or hunting type knives

you are the first channel that turn knife sharpening into satisfaction

Ah yes, rotate the knife to face your abdomen! Ugh

So you use them dry? No water, or oil?

How the hell are you supposed to know which angle to use ???

The ads for this knife sharpener are bs it said other knife sharpeners only keep the knife sharp for minutes

How do i sharpen a narrower knife blade that is shorter than the angle bock. For instance a paring knife or a boning/ filet knife.

What's the purpose of the hone?

My roller is locked up and won’t roll, just the rubber parts roll along the discs on each edge. How can I fix that?
