After 30 years of making prosthetic hearts and artificial blood vessels fly-fishing physicist Dr. Chris Underwood realised he could adapt the same technology to develop his D-Flex rod technology
D-Flex’ technology allows the manufacture of rods with an over-emphasised ‘spine’, meaning they are significantly stiffer bending one way than the other.
According to Underwood, the D-Flex cross section reduces stress loading, making casting control easier, more accurate and significantly more powerful, and can be used to make rods for fly fishing, spinning, waggler fishing, distance casting and even pole fishing.
