The Grinner / Uni knot is a multi-purpose fishing knot; as an avid fly fisher, its my personal favourite.
Commonly used to tie a fishing line to a hook, swivel or lure.
It is known for its strength and ability to hold well under heavy pressure. It ‘s relatively easy to tie and is considered to be a good choice for both saltwater and freshwater fishing.
How to tie a Grinner
- Hold the hook or lure in one hand and the fishing line in the other.
- Thread the gut / line through the hooks’ eye, once or twice (optional).
- With the tag end make a loop by returning the tag end back over the mainline.
- Pass the tag end around the mainline and through the loop 5 or 6 times
- Bring the tag end of the line back through the loop parallel with the mainline.
- Lubricate the knot by wetting it with saliva or water; pull both end to tighten
- Hold the hook / lure and pull the end of the main line to slide the knot gently to the hooks eye
- Make sure to pull slowly and evenly to ensure the knot tightens correctly.
- Trim the excess line.
It is recommended to practice the knot before using it on the water, as well as checking the knot’s strength before casting your line.
