The Triple Loop Knot is the strongest fluorocarbon knot around, probably due to its use of multiple loops in a complementary way to the stiffness often found in fluorocarbon lines. The knot begins with three consecutive wraps around the eye of the hook (or your terminal tackle of choice), which immediately gives it an efficiency edge with triple line backing. The triple loop structure works well for stiff lines like fluorocarbon but won’t fare as well on slippery braided lines, so you’ll need to employ the knot in the right situations.
Here are the knot strength efficiency numbers for the Triple Loop Knot as tested across the three major line types.
See the Fishing Knot Strength Chart for more data and details on the testing methodology.
