Eight-way hand-tying is an old technique that refuses to be improved. Eight strands of jute cord radiate from each spring, knotted in a set sequence so that the entire deck moves as a single surface and not a collection of separate points. There are faster decks — steel bands, sinuous wire, webbing stretched into place with a stapler — and there are reasons they exist. They are not the reasons we chose otherwise.
A hand-tied deck softens over time without collapsing into a valley. It holds a seated shape and returns to its original when the shape leaves. It does this because the tying is cooperative — each spring relieved by the springs around it — and because the cord is jute, which stretches a little under load and then remembers. The knots are set in a specific order because the deck has to be brought to tension in even increments, the way a tuner brings a string up to pitch.
One maker does the whole deck, start to end. It takes a day. It takes two. A sectional takes longer. Nothing about this is efficient. It is, however, correct, and a deck tied this way will still be a deck in forty years.
