Developed by Rupert Harvey over nearly two years of testing, refining, and on‑water proofing, the Flex Claw is the next evolution of the 3D Strong Arm concept. Built for tiers who want a claw that looks right, swims right, and fishes hard.
The original pioneers of 3D‑printed crab parts Stream Art Design created an incredible two‑part Strong Arm claw that fish responded to immediately. But it didn’t match the profile and behaviour Rupert was chasing. So the redesign began.
The Flex Claw is built around a central Flex Spine that keeps the claw balanced and prevents the “one‑sided” problem common in earlier designs. The angle is set by the tie‑in tab, meaning no UV glue is needed to position the claw. When tied correctly, it will flip the crab hook‑point up every time clean, reliable, and consistent.
After extensive testing, the Flex Claw now delivers the look, movement, and durability Rupert wanted from the start.
