KnotStep: Tie Any Knot

Tie the right knot for the job, even with no signal.

KnotStep is a calm, illustrated guide to 44 knots that matter on the water, on the rock, and at camp. Every knot has clear numbered steps, a hand-drawn diagram for each step, a holding-strength rating, a plain use-it-for line, and an honest watch-out note so you know its limits.

Grouped by what you are doing:
- Fishing: line to hook, line to line, and reel knots like the Palomar, Improved Clinch, and Blood Knot.
- Boating: the Bowline, Cleat Hitch, Clove Hitch, Anchor Bend, and more.
- Climbing: the Figure Eight tie in, Double Fisherman's, Prusik, and other essentials.
- Camp: the Taut-Line Hitch, Trucker's Hitch, lashings, and quick releases.

What you can do:
- Follow step-by-step instructions with a diagram drawn for every move.
- See each knot's holding strength, difficulty, use, and safety note.
- Search by name or by purpose, like anchor, loop, or join.
- Save the knots you actually use to your kit, then see your kit's average holding strength and a by-use breakdown.
- Compare every knot for a job, ranked by holding strength, so you can pick the strongest or the easiest strong option.
- Export a printable Kit Card PDF or a CSV of your saved knots, for the dry bag or the glovebox.
