Hyde Tools 01140 1-1/2" Stiff Black & Silver® Stainless Steel Chisel Edge Putty Knife

the flat back goes toward the surface for shave-scraping (edge parallel, no corner dig); roll the bevel down to get under a lifted film. Learning which way the single bevel faces is the whole skill. Low angle: 15–30° — the blade should shear and slip under, not chisel in. Push for power, pull for control. Keep it keen: a chisel edge lives or dies by its bevel — dress it on a stone held to the bevel angle when it dulls or rolls; a dull chisel skids where a keen one slices. Stainless in practice: the payoff is wet removal with no ritual — wallpaper paste, water-rinse stripper, damp residue all wipe off with no rust bloom. A carbon chisel (the .075" 02200, a size narrower) holds a marginally keener edge for dry force work but wants drying and oiling; for anything wet, stainless is the working answer.
