Steel Scraper: a Clockspring Blade in a Slotted Handle (Shop Notes, 1912)
A handy scraper for dirt and grease on machinery or old paint on uneven surfaces: a stout piece of clockspring set in a slot sawn in a short wooden handle, bound with wire or a ferrule.
Variable: spring size sets strength and flexibility; a double scraper adds a triangular blade for carved or indented work.
