Flax ripple
A flax ripple is a comb-like tool used to strip seed heads from harvested flax stalks. Norges Linforening uses the Norwegian name linrepe for flax-processing equipment. English museum texts call this operation rippling and the tool a ripple or rippling comb.
This must be distinguished from hackling. The ripple removes seed heads from stalks, whereas a hackle is used later in processing the fibres. Freilichtmuseum Hessenpark describes an iron comb through which dried bundles of flax were pulled. A toothed metal tool is therefore not automatically a flax hackle, even when the shape appears similar.
For identification, record the number, spacing, length and mounting of the teeth. Establish whether the comb survives alone or with a wooden base, and distinguish original attachments from later display fittings. Compare form and wear with documented tool types before assigning a function. A modern reproduction may follow traditional construction, so dating requires more than the shape alone.
