Riverworks Rod Company Carbon Fiber Grip Conversion

I’m a convert! Riverworks Rod Company is offering high performance carbon fiber grips for Oni tenkara rod models.

While the cork grip was starting to look rough, there wasn’t anything “wrong” with the rod. Just the opposite really – It’s beat up because it’s my favorite to fish. In my view, the Nissin Oni Zerosum Honryu 395 is a strong candidate for the best “one-and-done” tenkara rod on the market. It’s well balanced, and able to deliver a nearly immediate recovery. This means it stops wobbling almost instantly after the cast stops, which is a big factor in accurately casting and controlling light lines. I was able to make it do everything I wanted to do with it, comfortably. No complaints with the rod prior to deciding to convert the grip. It was already, in my view, a “perfect” tenkara rod. 

Riverworks Rod Company is known for engineering some of the tenkara-verse’s most specialized fixed line rods. Company owner Jeff Lomino brings a nearly obsessive attention-to-detail to his products. The company’s signature tactical nymphing rods have a cult following, largely due to the ZX rod line’s high performance blanks. Riverworks rods stand apart for another reason too – Jeff has pioneered what I believe to be the ultimate tenkara rod grip. 

Does the grip really matter that much? A month ago I would have told you “no”. I would have said “while I love the feel and look of the cedar wood grip on my Nissin Air Stage Fuji-ryu, it doesn’t seem to impart any extra capability to the rod”. I did not feel held back by cork, or even EVA foam, which is my least favorite grip material. As long as the shape of the grip is comfortable in my hand, I’ve never felt it offered potential for improving. So why would I even consider changing the grip? 

I’m not afraid to admit that the first reason was simple: Riverworks carbon grips look SHARP! The black carbon fiber gives me old-school stealth fighter vibes. The second reason, the important reason: Jeff has engineered a grip that delivers energy transmission at a level I’ve never experienced on any other rod. That carbon fiber grip is wrapped around a high density foam core, which is adhered to the blank. This means no gaps to deaden vibrations – when extended, the rod is effectively a “solid” single piece from the grip to the tip. Any vibrations taking place at the end of a properly tensioned line transmit instantly and completely to the grip. 

You are probably thinking – “I can already feel strikes in my hand, through the grip.” Respectfully, my answer must be…”not like this”. A month ago I would have agreed with you. A month ago I had not felt the differences myself. This grip delivers extreme sensitivity, with vibrations clearly transmitting all the way down the rod to the very bottom cap. In the cast, drift, set, and play, I can feel more details than I can with other grips. Each fish I’ve caught with the convert felt noticeably unique and nuanced. Adding additional mass and material made the rod a few grams heavier, which did alter grip’s weight and balance – for the better! The finished product had improved its balance and added some extra punch in my cast – without any negative changes to performance.

Each fish I’ve caught with the convert felt noticeably unique and nuanced.

I was absolutely satisfied with this rod before converting it. Jeff took what I thought was already a “perfect” rod – and significantly improved its performance. Riverworks carbon fiber grip conversions are offered exclusively for Oni Type I, II, III & Honryu rod models. If you want to take your favorite rod to the next level, a Riverworks convert grip will deliver – it did for me!

  1. My Riverworks rods are among my favorites and a big part of that is the Carbon Fiber grip. I don’t own any Oni rods, but I can imagine what it feels like to bring together some of the best rods on earth with that grip.

      1. I’ve been on a waiting list for about a year for the Honryu 395. That reminds me, it’s probably time to check in on that. No updates in a long while.

    1. From the link at the end of the post to Riverworks info page:


      Price does not include initial shipping of the rod to our shop to begin the process, or insured return shipping once the conversion is completed.

      What it does include—

      1. Complete removal of EVA or Cork grip on the rod

      2. Construction of a new CUSTOM Carbon Fiber Grip especially for your ONI model (Special requests for sizing and length are discussed prior this step in the process)

      3. The original ONI butt cap and insert are used in the new grip installation, but the Winding Check will need to be replaced. We have several options and colors that can be used (Again, this is discussed prior to starting your project)

      4. The original epoxy on the threadwork of the original rod must be stripped off prior to the new grip installation. We provide new threadwork and overcoat the original epoxy footprint and the CONVERT logo with new premium epoxy. We can also touch up epoxy on the vulnerable area at the top of the butt section (where the nose cap is)

      5. Any additional graphics or finish is an extra fee and is discussed prior to your project start
