2. Preference for reliable, easy‑to‑release knots

"I've become a huge fan of the secure knot. Holds easily as well as any double knot I have ever seen, with the massive advantage of easy release." — tzeric

3. Importance of a core set of versatile knots

"My favourite knot is the bowline. Non‑slip loop, very strong, easy to tie, easy to undo. Can be used for tying two ropes together, ropes to things." — JR1427
