    “Disappeared”! after that it was me and the target! Perfect construction, technically and aesthetically! Thanks and highly recommend!

    Top quality piece of kit.
    It has really made a big difference to the feel of the bow and it’s nice to find a grip that actually fit’s large hands

    I’m very happy with the grip. It fits the raiser perfectly, even though it’s an old one. The surface feels dry and sticky which helps a whole lot as I have rather sweaty hands. It’s also very definitive – has a position that it wants to go in and forces itself into a specific place in my hand. Overall – perfect buy.

  6. John W. (verified owner)

    Very good .subtle slope design across grip puts your hand in correct position .
    Will be ordering another for my practice bow after Christmas.

    Item arrived well packaged with the added bonus of a pen and key ring. Before fitting the grip, I set my bow up and shot a couple of ends to warm up. The R-Core grip fitted perfectly and was the angle I needed without the use of epoxy. It looks awesome, feels solid and the thumb placement is great for keeping those groups tight. Very impressed indeed, I may even buy a second grip in Unicorn Poop.

  14. David V. (verified owner)

    The color is perfect. I like the unique angles of this grip. It fits my hand perfectly. The glitter material is subtle, but gives the grip a nice non-slip texture.

  15. (verified owner)

    Grip is really good. I had one 3d printed for me by a local guy but the K.T.E.E.N.O.S is way better. One of the best archery equipment i ever purchased. Shipping is fast also considering I am in China and there’s a pandemic going on.

  16. Roger Smith (verified owner)

    This grip allows the same grip on bow, time after time. I will soon order one for my G2 Gillo. Thanks.

    Great service and a great product.
    Do your bow a favour and get one you won’t be sorry.

  20. Volker Ladurner (verified owner)

    This grip is excellent! I started with a Master grip and already liked that one, but the Kteenos (especially in the low variant) fits my hand and my shooting style even better. It’s so comfortable (the Boring Black material feels very nice) and my hand just slips into the right position. The thumb spacer is extra helpful!

  21. Gradimir M. (verified owner)

    Best investment I did for my bow ever!

  22. Ben Watterson (verified owner)

    feels great in the hand. Better grip in wet weather or sweaty palms.

  23. Harm W. (verified owner)

    The grip gives me great alignment of my hand. The ‘sparkle’ material gives the grip a nice anti-slip texture while still being smooth. Solid fit on my riser (would not expect otherwise because it is in the list of supported risers. Also excellent and quick customer service by Aris, in giving advice as well as support!

  24. Randall (verified owner)

    This Grip fit perfectly on my riser (Gillo G1-27) and I am very pleased with how my hand fits on the grip. I have a large hand and no stock grip feels comfortable. For example: I use a a 5″ tennis racquet grip. I sent R Core dimensions and pics of a grip I made for myself. They made enlarged the KTEENOS grip using these dimensions for the same price. I’m very pleased with the quality and I will be ordering more for my other risers. If you decide to order in 2020 and I encourage you to order something, be aware that shipping takes forever due to the pandemic. Forever = 46 days from Greece to Minnesota USA. This is good company to deal with. I had a good experience.

  25. Jochen (verified owner)

    Fantastic form and function, thanks Aris for that great grip and the endless help on which one of your portfolio to choose!

  26. J. Kwan (verified owner)

    Great product, my hand slips right into place and fits my Gillo G2 like a glove. Excellent customer service from Aris.

  27. Matthew G. (verified owner)

    The grip has given me a far more consistent hand position on the bow which has led to better scores. It does wobble a little and rub my thumb knuckle but to be honest I would not go back to my old grip.

  28. Phil Grundy (verified owner)

    Opened up a new experience, with old grip would have to reposition my hand each shot. Not now, grip the bow falls into correct position and shoot. Like it so much going to replace GMX WITH ONE.
    Can’t thank you enough.

  31. Craig Doherty (verified owner)

    I really enjoy my Gillo G1 barebow setup but the grip was not comfortable. Research led me to RCore. After a few emails back and forth I ordered a KTEENOS In the size recommended. 100% satisfied with the grip. Shooting and comfort improved apppreciablly.

  32. GERY (verified owner)

    Well made, easily repeatable hand position.

  33. Alexander K. (verified owner)

    Bought it with my CAERUS. This grip is very nice and the lifeline ridge helps to control hand position. However my personal no2 because the CAERUS fits MY hand even better

  34. Chris Hodgson-Bates (verified owner)

    Aris did a brilliant job for me. If you are not sure what type of grip that you want, Aris will answer the questions you put to him the best that he can and help you out.

    The color is awesome and it fit perfectly on my SF Forged+ riser. If I decide to change my riser in the future, it will definitely have an R-Core grip!! That’s for sure!!

  44. Eric R. (verified owner)

    Nice grip, fit my Samick Ideal well, nice defined grip !

  45. Dusan (verified owner)

    Amazing grip, fits pretty well, although I expected that the surface was a bit wider than my Mybo. Shipping was fast. I like the textured feel, which prevents the hand slipping. The lines from 3D printing are slightly visible, but that’s expected with this manufacturing technique.

  46. Alexander M. (verified owner)

    Purchased the KTEENOS grip and it is the perfect grip for me. Not only was the product amazing but so is Aris. I made a mistake with my order that I noticed last minute and he fixed it for me without any hesitation. Incredible!

  47. Alexander (verified owner)

    This was my seconds Grip Form R-Core. The Master was good, but the KTEENOS is for my large Handy more comfortable. I really like it! Thanks!!

    Service was exceptional, communication the best I have ever experienced, the product is out of this world. The grip I have needed from the beginning, my shooting proficiency has increased. I will never take this grip off my bow.

  60. Henricus CM (verified owner)

    Quality of the product ( design, colour and finish ) is impeccable.
    Rating 4 instead of 5 has nothing to do with the product, but is related to the ‘feel’ as a whole.
    Features as antis slip pattern and lifeline-ridge feel good (so I can get rid of the tennisgrip cover)
    I was pleasantly surprised by the overall service during ordering process and information about shipment.
    For sure me and fellow club members will return to this address for grip issues.

  61. roger (verified owner)

    Excellent grip, really comfy, higher than OE spec, I like the serrated face and the ‘edge’. Excellent service and tracking to my door. Using it just three days after ordering. Recommended.

  65. Simon W. (verified owner)

    After trying the master which whilst good still didn’t quite hit the spot I decided to try to this one as it’s wider and it’s really done the trick immediately had a better hand position and a solid point to press against. In the printed wood feels great

  66. Paulo simoes (verified owner)

    The best o é for me

  67. Tristan Armes (verified owner)

    Very easy to make the order and I knew I wanted the KTEENOS because I have big hands. Feels good in the hand and fits much nicer than my standard Hoyt grip on my Alero. Got the teal glass style and love how it looks on my bow. I’m glad I got the pyramidal anti slip on it. I was worried it might be too pronounced and dig into my hand, but it’s soft enough to go unnoticed, while making sure my hand doesn’t slip around. I got the high angle which feels tighter and *hugs* my hand, making my hand placement more consistent. Only slight downside was the postage. UPS sent it around the houses (Italy, Hungary, back to Italy, Germany etc..). This took almost a month but it did eventually come. Not the fault of Rcore though! Product is fantastic and would buy again in the future, thanks!

  68. Kurt H. (verified owner)

    I purchased the KEENOS, high grip, Jurassic Amber glass, no pattern, with a lifeline ridge.

    The grip has a finished high quality look, is see-through which is really interesting, and fits my Formula RX perfectly. My riser is green and the contrasting orange/amber color looks great.

    I like the way the bow reacts after the shot, which is better than the previous grip I was using. The grip fits my hand and is comfortable in the palm throughout the shot cycle. I’m looking forward to shooting it in the coming summer months to see if it wears, and if sunlight fades the color.

    After shipping costs the grip is rather expensive, as I live in the US and the grips ship from Greece. In my opinion the total price is pushing the value proposition, which is why I didn’t rate five stars. I may change my opinion as I shoot the grip over the coming months.

  85. DIMITRIOS M. (verified owner)

    Pros: Quality product, fits very well on the bow. Nice feeling on the hand.
    Cons: I bought the grip without the anti slip pattern, so I have to glue a thin sanding paper on the grip to stabilize my hand because it was slipping.

  86. Vincent (verified owner)

    Tolerances on the grip correctly matched the riser I own (WNS Motive FX, 25 inches). The finish on the grip itself was, visually, not as nice as I had hoped, but the fact that some of the texture from the 3-D printing process (I’m assuming it’s 3-D printed based on the look and feel) remained actually worked out in my favor when using adhesives for further customizing the grip to my hand shape.

    This is a good replacement grip for the type of riser I own.

  87. Marko Sundman (verified owner)

    Very fast divery. 3days.

    Item is not what I ordered, the thumb positioner is really flat a lot lower than the one from the picture online when ordering. I request to have the lifeline ridge and it doesn’t come with the ridge

    The shape of the grip was spot on . I would like a little more grip for my palm . I made some mods and now it is a 10 plus . I think the shipping cost of over $ 20 dallars is a bit much . The good news is i love it .

    Beautifully made. I’ve gone for the Irocco Wood version with hexagonal anti-slip pattern with life-line ridge. Looks stunning – shoots even better. Although my hand-shape is not an exact fit (little gap at the neck), it always finds the same position and my groupings have definitely improved (shot my first 60-end within a week – I blame the grip). For UK customers, please be aware you have to pay a substantial import tax these days…

    This grip is better than I had hoped for. I can already see gains in my groups by having a much better fitting grip. I am pleased beyond measure. Love this grip. It’s like a brand new bow that’s much more accurate to shoot. Shipped much quicker than I had expected. Excellent product I highly recommend. If you hunt with a satori, you will want this on your bow. Game changer I tell ya.

    I have tried a couple of the different grips and this is is by far my favourite, my only negative is that due to the ‘hugging’ nature of the grip the plastic one is a bit rough, as the top of my thumb is constantly against the layering of the printed plastic causing some rubbing. But overall love these grips and the variety and colours available are brilliant, always excellent service and arrive quickly.

    Aris and the team at R-Core are nothing short of the best in customer service and quality products. I changed my order at the last minute but with great and prompt communication that wasn’t an issue. My package went missing on its journey to me but a quick email to Aris and he got it sorted out. The grip itself is great in the hand and has a nice snug fit on the riser. The hexagonal antislip texture feels great and the colour is better than I expected. The only issue I came across was the recess for the washer wasn’t quite big enough for the washer, some modification to the washers and problem solved. Highly recommend giving these grips a go!
