Model

Introducing the Functional Tennis Saber, available in 3 weights.

  • Mid (300g unstrung)
  • Lite  (265g unstrung)
  • Junior (240 grams & 2 inches shorter, for 6-10 year olds)

ℹ️ The Saber will arrive to you strung and ready to use 😊 

⚔️ The Saber is an on-court training aid that plays like a normal tennis racket but with a much smaller head size. This unique design with its 37 sq. inch head forces players to focus on ball tracking, optimise footwork, and execute a clean, efficient swing to connect with the ball. 

🏭 Made from a composite material in the same world-class factories as other major brands it comes in a weight of either 300 grams or 265 grams or the new shorter 240 grams version. One coach has said "Straight out of the bag, it feels expensive and very well made"

⏱️ Using it for just 10 minutes as part of your normal warm-up routine will make you a much more consistent player, winning those points that make a difference in matches.

💬 Players have said it's a “game-changer” providing a “great feel” and a “must-have for every coach and serious player”. 

🥷  There is no need to change your grip or adjust your playing style to be efficient, simply swap your racket for the saber and you will feel at home right away. We’ve had a top International Junior playtest, and his dad reported back “he doesn’t want to play with his normal racket anymore!”.

Recommended String Tension

  • 13.5 KG / 30 lbs

It takes just under 5.5 metres to restring so we recommend you cut 6 metres of string.

A normal set of strings is 12 metres so you will get 2 restring from your normal set 😀

The saber has a bigger hitting area compared to the pointer, it's more comfortable on the arm and less forgiving but still difficult.

Also, it allows you to easily hit spin with your normal grip, unlike the pointer where it's harder to hit spin and you have to adjust your grip.

Plus wait til you see the fun you have with it!!

Yes it does. The string header card doubles up as a stencil. Do not bin it!

Just What I Needed

I noticed on videos I took of my practice sessions that I was consistently hitting the ball too high on the string bed. When I saw the Saber, I thought that would help me hit the ball on the sweet spot more often. I used the Saber for the first time this week with a ball machine and was very pleased with the result. I framed most of the first few baskets of balls, but then started hitting the center of the strings consistently. I then switched to my regular racket and noticed a significant improvement in hitting the ball in the center of the string bed.

The Ultimate Training Racket – A Game-Changer!

I recently got my hands on the Functional Tennis Saber, and wow—what an absolute game-changer! First off, huge shoutout to Fabio for creating such an incredible tool. You can tell straight away that this isn’t just another training racket; it’s a precision instrument designed to reveal every little detail about your technique. From the first few hits, you immediately realize where your strokes need work. There’s no hiding behind off-center hits—either you hit clean, or you don’t! But that’s the beauty of it. After just a few sessions, I noticed a huge improvement in my timing, feel, and control. It forces you to refine your strokes, and once you switch back to your regular racket, the difference is insane—you just feel the ball so much better. If you’re serious about improving your tennis, I highly recommend getting the Saber. It’s not just a training aid—it’s a must-have for any player looking to fine-tune their game. Thanks again, Fabio, for bringing such a unique and effective tool to the tennis world!

It’s a great tool for tennis coaches. I’ve mainly been using it during warm ups with advanced and higher level players. It increases focus and highlights deficiencies in stroke mechanics.
