Carp Rig Length Measuring Tool

A 3D printed ruler designed to measure and tie carp rigs with precise length. To use it, place the hook eye into the selected hole with the desired length marking, wrap the line around the bottom peg, and tie the knot. The tool has a built-in 5 mm tolerance, which is naturally compensated by the knot. Simple, accurate, and very handy for preparing consistent rigs every time.
