These look very nice rods , the only other shaped black the springs to mind other than oval blank was a hexagon shape by Bruce&Walker the hexograth these were heavier rods though

Thanks for your comment - the Hexagraph was very heavy, these are super light. Have a look at www.d-flex.com for more info. Cheers and tight lines.

Hi, I think Dawia made triangular D profile blanks over twenty years ago for IGFA boat rods. One of the more expensive blank makers produces blanks for Pac-bay in America, based on the same blank profile. Nothing new in the way of innovation. Penn and Able also produce saltwater fly rods in the same profile, for both the American and Australian market. They are quite expensive and rival sage and G-Loomis. You might need to check copy and patent rights. You wouldn't want huge tackle giants to issue lawsuits.

I've just asked a Friend of mine who is a consultant for Hardy. Concerning triangular profile fly rods. Apparently quite a few companies experimented with the idea in the early 90's. In America several companies use a sintrex (Hardy patent) based resins in their triangular shape profile blanks to avoid breakages. Apparently the triangular profile works on the same principle as a long bow with push and pull. Same as a split cane rod which always wants to go back to being straight. In the early 2,000's companies tried oval shaped blanks in fly rods which led to the discovery of sintrex and nano resin technology to help reduce breakage. However the oval blank profile never took off and didn't come to anything. A company called Bruce and Walker tried hexagonal blank profiles in both fly and coarse rods, they are very, very expensive to produce due to the profile shape. They are also heavier than round profile blanks. They used the hexagonal profile due to breakages caused by flat surface profile problems (kinking). Hence the use of spherical glass based resins added to carbon to make the blanks. Food for thought ? In the 80,s one company tried square shaped profile blanks to make match rods but, found that the finished rods were brital and kinked. So they rounded the square profile to prevent kinking . However when they looked at the new profile it was round , circular . There's a surprise.

We'd be interested to see the evidence of triangular rods that have been made by anyone in the industry, as D-Flex owns the patent for rods that are triangular.

hi, today I spoke with my old friend John Holmes, a renowned rod maker. John has over the last fifty years worked with some of best rod Blank manufacturers in the business. He's now eighty years old and still builds custom rods. I showed him your video ,which he watched with interest. He pointed out that the person in the video is not the world's best fly caster or that the blank is a little too stiff for his style of casting. He explained that rod blanks in a triangular profile are stiffer than these with round profiles. Apparently it's to do with the push pull effect when the blank is flexed. Blanks that have this type of profile are usually expensive to produce compared to round profiles. Carbon and carbon resin sheets are easiler to roll into round profiles and are therefore cheaper to produce. The idea of different profiles in rod blanks has always fascinated him . I asked him if other rod and rod blank manufacturers have tried or produced triangular profile products. His answer was Yes. He thinks that the first triangular profile blanks were produced by conoflex for beach casters, he's pretty sure it was marketed as the long bow as it had the same profile shape as an English long bow. It wasn't a great success due to stiffness of the blank and the cost to produce (the problem was the rod joints) .Most rod builders made decent boat rods out of the top section. He also said that an American company produced a much better triangular profile blank by basically splitting carbon graphite blanks of different flexible curves and gluing the strips together, to create the desired curve and flex ,a little bit like making a split cane rod. He added that the idea was always best suited to longer powerful rod uses. He believes that salmon fly and spinning rods would lend themselves more to the technology. He's definitely believes other companies have produced triangular rod blanks. Mainly in far east and America. Jushgang technologies in Taiwan make sea fishing rod blanks. Roadhouse, North fork composites, Rainshadow, Blackhole, Phenix, MHX,T-Russel . All produce rod blanks of many different types and shapes. Of course there's Suzuki blanks of Japan. We all find this a fascinating subject, John's final comment was that he wishes you luck in this project. Check out the new Loop X7 fly rods they have a 2:3:2 profile to enhance performance. Good luck and success in your endeavor. Just remember there's no such thing as the perfect rod particularly fly rods. Everyone casts differently and manufacturers make no two fly lines the same particularly in line weight. Tight lines.

@@d-flexfishingrods9427 apparently the Loop X7 is the best fly rod made at the moment, due to its profile shape. They are very expensive, you don't get much change out of a thousand pounds for the trout models and the salmon rods are well over a thousand pounds. I've asked Loop to lone me a 10 foot 7 weight to test. Would be interesting to see how it compares with the brand new Hardy and sage rods,that I have on test . I'll include you in the feedback. Tight lines..

@@d-flexfishingrods9427 just been reminded by a friend from Harrison. David Norwich produced triangular profile salmon and trout fly rods. Apparently the idea was sold to an American company. Sage are releasing an egg shaped profile blank in the UK later this year. Already available in the States.
