Description

Introducing the Oni Grinder, a sensual masterpiece where sharp, fierce design meets soft, silicone pleasure. Inspired by the Oni of Japanese folklore, this grinder boasts devilish details, including textured horns and a sinuous tentacle tongue that teases and tempts with every move. The cherry blossom base adds a delicate, unexpected touch, balancing strength and beauty in one captivating design.

We loved designing this beast, and we can’t wait to get it out into the world and start experimenting with all the exciting color combinations you choose.

Whether you're strapping it to a pillow, your thigh, or even your forearm with its fitted black nylon straps (2.5ft / 0.7m each) and quick-release buckles, this grinder will have you in for one hell of a ride.

And for those who like things a little smoother, you can upgrade your Oni Grinder with our Silky Smooth Upgrade, offering a buttery glide thanks to an additive derived from Durian tree nuts. Just be aware of the slight nutty scent, and people with a nut allergy should avoid this option.

Award-Winning Pleasure That Finally Slayed The Dragon

Yes, we're legally required to mention we won the Bazowie Awards 2025 "Best Horror Toy" (we beat Bad Dragon, and no, we will NOT stop bringing this up at every opportunity). After years of being the underdog, we've officially graduated to "the company that slayed the dragon." Is this our villain origin story? Perhaps.

Product FAQ

What are grinders?

Sex toy grinders are specially designed toys with textured surfaces meant for grinding and external stimulation.

They're made for creating delicious friction against all your favourite external spots, whether you're rocking solo or turning up the heat with a partner.

For vulva owners, it's like having the perfect "on top" moment whenever you want it. And penis owners? Roll it up and you've got yourself a texture-tastic pleasure party!

Why are we so excited about grinding? Because sometimes the simplest pleasures are the best ones! We're bringing back that natural, intuitive way of feeling good that somehow got lost in the shuffle of "traditional" toys.

The best part? There's no wrong way to groove with a grinder. Whether you're flying solo or adding some spice to partnered play, these toys are all about finding your rhythm and owning your pleasure.

What is the vibrating bullet upgrade?

Do you want to take your grinder to the next level? Well, look no further! You can now add a hole and a Remote Controlled Vibrating Bullet right into the base of your grinder. Boom! Instant Vibrating Grinder!

We've even made sure that the hole fits most bullets perfectly, so you can use your own bullet or ours. Get ready for a grinding experience like no other and feel those intense vibrations all over your grinder!

What is the silky smooth upgrade?

We offer the ability to upgrade your grinder with a silky smooth finish. To achieve this silky smooth finish, we use an additive derived from Durian tree nuts, ultimately resulting in a more luxuriously smooth feel that glides rather than grips like other silicones. This also gives them a velvety matte makeover that feels as good as it looks.

However, we recommend you avoid the silky smooth upgrade if:

You are allergic to durian, tree nuts and tree nut derivatives or musk thistle seed
You are sensitive to smell - Normal silicone has no scent however using silky smooth will give the silicone a subtle, nutty scent.
You want a glossy finish to your toy.

The super silky upgrade is only available on our sex toy grinders and both of our made to measure penis extenders.

What are the different colour options?

We offer 6 different colour styles, though not all are available on every product.

Surprise Me Basic - Leave the decision in our capable hands and we'll choose a solid colour that compliments your toy selection.

Surprise Me Premium - Leave the decision to us and we'll get creative with two or more colours. We love this choice as it allows us to get experimental with all of our colours, often resulting in our best pours.

Solid - One colour that will run evenly throughout your toy

Fade - Two colours combined that are gradually blended together. Colour 1 will be the tip of your toy and Colour 2 will be the shaft and base.

Marble - Two colours combined resulting in a veining effect similar to classic marble.

UC Trademark - This is a product-specific colour. The main image of the product is the UC Trademark colour.

For more information, take a look at our colour guide.

Why do you only use platinum silicone?

We use platinum silicone so you get a toy that is non-pourous (meaning when you clean it, it gets fully clean and can't transmit bacteria), doesn't smell, is body safe and feels fantastic.

If you'd like to learn more about cleaning your toys, read our sex toy care guide.

What do the colours actually look like?

Check out our colour guide to see exactly what our colours look like. But please keep in mind, each toy is hand-poured, so no two are exactly alike!

Do the grinders come with straps?

Yes, the grinders do come with straps! Each one includes two black nylon straps, each 2.5ft (0.7m) long, with quick side-release buckles. You can strap it to a pillow, your hand, thigh, or forearm for hands-free grinding fun.

Reviews

Easy Favorite!

Toy: This is my first grinder and purchase from UC. For me, there was a bit of a learning curve and experimenting with placement to get the most out of this toy. Once I figured it out, it was a smooth ride 🤤 The super soft firmness is perfect; I don't believe the squishy soft would've given me the desired result. Definitely check out the firmness guide! I'm also really glad I upgraded to silky smooth. I don't have to add any extra lube to help reduce friction; I'm practically gliding lol. There is a nutty smell, but it wasn't overpowering thankfully. The facial features and tongue are perfectly placed and I honestly can't complain lol 👀 I wish I'd gone with a darker brown and chosen my color arrangement better, but that's purely a "me" problem.

Customer service: *chef's kiss* Very patient with me! I greatly appreciate that, especially since this was my first time ordering a customizable toy and I was all over the place with my request. Email responses were prompt and polite. Thank you 🙏

Overall, 10/10! Y'all have a new repeat customer. I already have my eye on a couple things 👀 💖

The ONI one for me ♡

Absolute LOVE this toy!! It's so soft, easy to use and gives a fair few ways to use it. I'm disabled and have mobility issues, but this Oni grinder is easy to use for that much desired stimulation! Hold the horns and let the tongue explore, slip in a horn and grind the nose, or rub its face everywhere, the options are boundless :D

Whats not to love???

I love, love, love (imagine an increasingly appreciative tone) this wonderful sculpt!!! I was captivated by the design since I first saw it. But having this grinder in-person genuinely is like a work of art (I actually would wear it as a part of an outfit if that weren't so ~salacious~)
I went for the "premium surprise" colours and I'm sooooo glad I did, trusting the artist to make a good decision with their own design is the way to go!!
My oni came in a shimmering swirl of magenta and dark blue-grey slate. I adore the combo 😍
Sometimes I'll just sit and appreciate the craftsmanship because small businesses just do it RIGHT!

Now for performance---
After a few test runs; I throughly enjoy this toy, at times I wonder if I should have gone the super squishy route, but as a fan of pressure I think the soft squish was the right way to go for me. (Good to keep in mind if you like a softer ride though)
There are so many positions to enjoy this toy (it's giving "gotta try 'em all!") And I look forward to introducing it into play with my partner too 🫡

If you have been looking at this listing (while waiting for a paycheque.. longingly staring and stroking your phone screen) JUST GO FOR IT!! You won't be disappointed!

(Not to mention, given that this came all the way from across the pond... after the order was finished it arrived so quickly! I was pleasantly surprised)

(In my photos he's freshly washed out of the box, water droplets were an artistic choice)

woag

amazing quality, looks gorgeous. this is my first grinder so I'm still sorta figuring out how to use it for the best... "results." clean-up is a teensy bit annoying but that's because I'm lazy and the design has a lot of intricate patterns in it. I got the silky smooth upgrade and was fascinated with the way the silicone felt on my hands.

First Grinder Toy

Ok WOW. I was not sure what to expect when ordering a grinder toy. I knew I wanted one in general, and this one looked so damn cool I HAD TO have it!

I’m so happy I ordered it! It’s a little bit of a learning curve if you are not used to this type of toy, but once you figure it out, WOW it’s worth it.

I’m also mind blown by how they managed to create an ideal colour mix for me. I put in the surprise me premium option and when I opened the box I was absolutely flabbergasting in the best way that somehow intuitively they just KNEW one of my favourite colours.

Customer service was absolutely lovely and this is swiftly taking a place beside my magic wand as one of my favourites.
