The Flitch
A flitch is a thick slab sawn from a log with the bark left on one or both edges. It is the first cut — the outermost board, where the saw meets the round of the trunk and the plank carries the tree's natural edge. In flitch sawing, the entire log is cut into parallel slabs, then the slabs are stacked back together in order, numbered, and sold as a set. Opened like a book, adjacent flitches show mirror-image grain: the same knots, the same curves, the same color changes reflected across the saw cut. Cabinet-makers buy matched flitches to create book-matched panels — two boards joined so the grain reads as a continuous pattern folded on itself. The flitch is the log opened but not yet abstracted. It still carries the shape of the tree it came from.
A flitch beam is a composite: a steel plate sandwiched between two timber beams, bolted through all three. The timber takes compression and provides stiffness. The steel plate takes tension and adds bending strength. The combination is stronger than either material alone and lighter than a steel beam of equivalent capacity. Flitch beams are used in renovation work — when an existing timber beam sags under loads it was not designed for, a steel plate is bolted in alongside rather than replacing the beam entirely. The original timber stays. The steel augments it. The beam becomes a hybrid that exploits what each material does best: wood's resistance to buckling, steel's resistance to breaking.
A flitch of bacon is a complete side of pork — salted, cured, and preserved as a single piece. Unsliced, uncut, the full half of the animal from shoulder to ham. The Dunmow Flitch is an English custom dating to at least 1104: any married couple who can swear before a jury that they have not quarreled, regretted their marriage, or wished themselves single for a year and a day is awarded a flitch of bacon. The prize is not a rasher or a joint but the whole side — the undiminished thing, complete and undivided. The custom has survived nine centuries because the conditions are absurd and the reward is literal: a year of domestic peace, proven publicly, rewarded with preserved meat.
Three flitches: a slab of timber, a reinforced beam, a side of bacon. Each is a complete section — the whole thickness of the log, the full depth of the beam, the entire side of the animal — preserved or used without being subdivided into smaller parts. The flitch is the unit before division: the raw slab, the intact side, the thing that becomes many things once it is cut but that has value precisely because it has not yet been cut.
