Knot Science & Testing

Knot-Tie Buddy forms a six-wrap Uni-Knot. Here is an independent knot-testing resource for anglers who want to look more closely at wrap count.

The source

Watch “06 Knot Science – Uni knot, braided” by Wide Open Outdoor Film. The table below summarizes the average breaking loads shown in the video’s charts: three pulls per configuration, using braid labelled 20 lb and 0.15 mm.

*The source chart calls this “Double Uni”. Following our designer’s identification of the method shown, we label it Modified (Improved) Uni-Knot here: pass the line through the hook eye twice before forming the Uni-Knot wraps. It is not the line-to-line Double Uni-Knot used to join two lines.

Why highlight six wraps?

Knot-Tie Buddy forms six wraps. In this particular test, improvement beyond six turns was relatively small compared with the jump from five to six. The Uni-Knot average rose from 12.57 lb at five turns to 19.84 lb at six, then 20.19 lb at seven. The double-through-eye averages were 17.27, 20.98 and 22.14 lb respectively. These are descriptive results from a small sample, not a universal optimum for every line.

What these results do not show

This is independent testing of knots and line, not testing, certification or endorsement of Knot-Tie Buddy. The line’s unknotted breaking strength was not established, so the figures do not establish percentage strength retention. Line, tying technique and test conditions can change the results. No knot-strength guarantee is implied.
