desguinzar

A rare, technical term from traditional paper-mill and textile work meaning to cut cloth or rags using a tool called a desguince, historically a step in preparing rag pulp for papermaking. Essentially obsolete outside specialized historical or trade contexts.

• En el antiguo molino, los obreros desguinzaban los trapos antes de hacerlos pulpa. — At the old mill, the workers cut up the rags before turning them into pulp.
• Pocas fábricas conservan hoy el oficio de desguinzar telas a mano. — Few factories today still keep the trade of hand-cutting cloth this way.
• El museo explica cómo se desguinzaba el lino en el siglo XIX. — The museum explains how linen was cut this way in the 19th century.

This is obsolete trade vocabulary from historical papermaking — a modern learner will never need it in conversation; cortar covers 'to cut' in every ordinary context.
