Kswiss Ultrashot 18K

Technologies

Pros

• ✓The 18K carbon face gives you a crisp, immediate response on the smash de 3 and on a víbora hugged tight to the glass, with the ball leaving the face without bleeding any energy on contact The Black EVA Mid-Soft core paired with the polypropylene honeycomb core soaks up vibration on blocked volleys and off-center hits, saving your elbow and wrist over long matches The GritSpin treatment bites into the ball noticeably on a cut bandeja and on kick serves, letting you open up angles that a smooth face would send back flatter Despite the diamond shape, the mid balance keeps a reasonably generous sweet spot: technical net play doesn't demand the pinpoint precision of other 18K diamonds The 38mm profile with 20x20mm rubber cuts down on EVA deformation at impact and speeds up energy return, which you'll feel in fast volley-to-volley exchanges

Cons

• ✗At 360-370g in a diamond shape, this racket punishes you on defense: arrive late to a low ball off the back wall and the weight drags you down, leaving the return short The 18K carbon is the stiffest, least forgiving surface in the range: any hit outside the sweet spot costs you direction and leaves a sharp, jarring feeling in your hand This isn't a racket for players who need help lobbing defensively from the back of the court; it demands your own arm strength and a long swing to lift the ball with depth The Mid-Soft feel cushions impact, but it doesn't make this a soft racket: players used to softer rubber will feel the physical toll in sessions over two hours

Kswiss Ultrashot 18K Review: Diamond Power With a Built-In Handbrake

The Kswiss Ultrashot 18K pairs the stiffest surface in the brand's lineup — 18K carbon — with a Black EVA Mid-Soft core and a 38mm profile, all packed into a 360-370g diamond shape. It's an unusual mix: explosive weave up top, cushioned rubber underneath.

That tension between materials shapes everything about how this racket plays. It's not a classic hard-hitting diamond that beats up your joints, and it's not a control racket dressed up as a power stick either.

What Does the 18K Carbon Face Actually Do on Court?

The 18K weave on the face is the stiffest surface K-Swiss makes, built for explosive shots and maximum precision. With more threads per bundle, the face deforms less on contact and returns energy with almost no delay.

On court that translates into a crisp response on the flat smash and on the víbora. The ball doesn't "sit" on the surface — it comes off exactly on the line you gave it, with no trampoline effect to bail out shaky technique.

The trade-off is tolerance. An 18K face forgives less than a 3K on off-center contact, and this racket proves it: miss the sweet spot and you lose direction along with a short, sharp vibration in the hand.

GritSpin and the Spin Game

The GritSpin finish gives the surface a noticeable roughness that shows up immediately on cut shots. The bandeja bites harder and the ball drops with more weight near the back glass.

It's most obvious on kick serves and on a víbora opened out wide. The texture lets you carve angles that a smooth face would send back flatter and easier for your opponent to read.

It's a bonus with a shelf life, though — the roughness wears down with use and court hours, as with any surface treatment of this kind.

The Mid-Soft Core and Polypropylene Honeycomb

This is the most interesting design call K-Swiss made with this racket. The Black EVA Mid-Soft core is combined with a structural polypropylene honeycomb core, aiming for a balance between control and vibration absorption to protect the joints.

The result is a middle-ground feel: firm on contact, but without the harsh, dead sensation of a hard EVA. The ball stays on the face a fraction longer — just enough to place a blocked volley or a dropshot without it flying long.

The 20x20mm rubber profile rounds out the equation. It's designed to cut down EVA deformation and return energy to the ball faster, favouring quick hands: in volley-to-volley exchanges at net, the racket responds quicker than its weight suggests.

Who Should Actually Play With the Ultrashot 18K?

This is an advanced-level racket built squarely for power. It calls for a player with solid technique, a full swing, and the ability to read the ball early. That 360-370g weight in a diamond shape isn't a number on a spec sheet — you'll feel it on every late preparation.

The ideal profile looks like:

1. **Backhand-side players** who finish points with a smash de 3 from the net.
2. **Bandeja and víbora hitters** who need real surface texture to pin opponents to the back wall.
3. **Physically conditioned players**, able to carry the weight through matches longer than two hours without their strokes falling apart.

It's not a good match for players whose game leans on long defense and the lob. This racket demands your own arm to lift the ball off the back of the court, and it won't bail you out on a rushed defensive return off the wall.

Where It Shines and Where It Struggles on Court

On attack, the Ultrashot 18K hits hard. The flat smash comes out fast, and the combination of a rigid face with the 38mm profile keeps the ball deep even when contact isn't perfect.

Volleys feel more comfortable than you'd expect. The diamond shape and the factory mid balance combine for a wide sweet spot despite the power orientation, making technical net play easier without giving up control.

The cracks show up on defense. A low ball off the back wall demands early preparation — get there late and the weight drags the shot into the net. The defensive lob isn't its strong suit either.

Verdict: Who This Racket Is Really For

The Kswiss Ultrashot 18K solves a specific problem: delivering 18K diamond power without the joint-jarring brutality of a hard EVA. The polypropylene honeycomb and Mid-Soft core act as the safety net on an otherwise demanding setup.

If your game lives at the net and you close out points with the smash and víbora, that 18K face gives you back exactly what you put in. If your strength is grinding it out from the back with patience, there are more forgiving rackets on the market that won't cost you as much physically.

Worth being upfront about: this is a padel racket for advanced players who already know what they're after. It doesn't teach you to hit hard — it amplifies players who already do.
