How to Use This Calculator
- Select the knot you plan to tie — Palomar, Improved Clinch, Uni, Blood, or Surgeon's.
- Choose your line material: monofilament, fluorocarbon, or braided line.
- Enter the line's rated test strength in lbs (printed on the spool).
- Read Knot Strength (%) to see how much rated strength the knot retains.
- Check Effective Strength in lbs — this is the actual force at which the knot will fail.
- Use the Recommendation Score to compare knot-line combos and choose the best option for your setup.
