The edged weapons fighting system known informally as Sevillian Steel (or Acero Sevillano) encompasses a variety of knife fighting arts that originally developed in Southern Spain, Italy, France, and throughout the Mediterranean. At the heart of the system is the deadly folding clasp knife – or navaja – popular with all Southern Europeans, regardless of the language they speak.

Over the last few hundred years, as these fighting arts spread and gained prevalence beyond Spain, Italy, and France, specific combat influences from other regions became incorporated into the system.

Today these fighting arts are represented by an assortment of weapons beyond the traditional folding knife: weapons such as the stiletto, the sword cane, and the walking stick. And today they also include the use of incidental self-defense weapons such as combs, pens, belts, jackets, bandanas, and even chairs.
