Metal on metal isn't one sound — it's a whole family of textures depending on the metal, the angle, and the speed. These 19 metal scratch sounds cover the working range: heavy steel scraped against steel for industrial textures, a knife edge dragged across a tin plate for a sharper rasp, hissing scratch sound effect material from a screwdriver across a panel, and the gritty grinding of a wrench dragged along concrete with iron filings underneath.
Game audio uses the short rasps for sword draws and metal armour movement — layered tight with a deeper hit at the front edge they read as 'blade against blade'. Industrial documentaries lean on the longer grinding takes to underscore factory footage without resorting to library music. Horror sound designers pitch the hissing scratches down an octave for door-creak replacement when an actual door doesn't deliver enough menace.
