Overview
Threading tippet through a cone-shaped barrel lines the line up with the hook eyelet, while a magnet holds the fly in place. Once threaded, the fly is flipped and the body spun to finish the knot.
The description is aimed at one frustration: tying tiny flies with cold hands, tired eyes or fading light. Magnet, barrel and spin finish combine into one small tool for that job. Material, size and weight of the tool itself are not given, so judge it from the description alone.
Who it's for
A trout or midge angler rigging small flies on thin tippet at dawn or dusk. People who already tie knots by hand without effort, or who need exact size and material data, gain little from a listing this thin on specs.
Pros and cons
- Magnet holds the fly in place
- Cone barrel aligns line with eyelet
- Spin finish completes the knot
- Compact enough for vest or pack
- Tool dimensions and material not listed
- Hook size and tippet range unstated
- Package data only, no product weight
Performance notes
The magnet fixes the fly so both hands are free to feed tippet, and the cone-shaped barrel funnels the line toward the eyelet instead of leaving it to find the hole. Flipping the fly and spinning the body then wraps the knot without fine finger work. Results depend on the hook responding to a magnet and on the fly size staying within what the barrel can guide, neither of which the listing details.
