Hyde Tools 02600 4" Extra Heavy-Duty Stiff Black & Silver® Chisel Scraper

full fist on the nylon handle for power, the heel of your palm behind the tang, and push from the shoulder — a 4" blade wants body weight, not wrist. Angle: low, 15–30°; the chisel should shear the coating off the surface, not plough into it. Bevel orientation: present the flat back of the single bevel toward the substrate to shave residue flush; roll the bevel toward the work only when you deliberately want the edge to bite and lift a thick plate. Edge care: high-carbon steel files to a keen, square scraping edge and holds it well, but it dulls on old paint and dents on grit — dress it with a mill file held square the moment it rolls or nicks, because a damaged edge on a wide blade prints every flaw across four inches at once. Rust discipline: carbon is not stainless. Wipe the blade dry after wet work and after any solvent or stripper contact, and a light oil film keeps the bloom off between jobs — the maintenance tax you pay for carbon's keener, more easily restored edge. Keep it loaded: on cupped or uneven surfaces, take narrower bites within the blade's width so the whole edge stays in contact and the corners aren't doing the work alone.
