Loon Ergo Knot Tool
Loon Ergo Knot Tool is an ergonomic tool designed for tying nail knots quickly and consistently when assembling a fly-fishing set-up. It provides a purpose-made alternative to an improvised tube or similar object, helping the angler retain control of the line wraps as the connection is formed.
The tool is particularly useful when joining a fly line to a leader or leader butt section. It supports the wraps and helps guide the tag end through them, making it easier to produce a neat, compact knot. Its ergonomic shape offers a comfortable grip for preparing tackle at home as well as carrying out adjustments or repairs beside the water.
Clear tying instructions are supplied with the tool. Before relying on a new connection, it is worth practising with spare pieces of line and leader material, then tightening the finished knot evenly and testing it under steady pressure. After fishing, simply clean and dry the tool before returning it to a tackle bag, vest or workbench storage.
