Veritas Super-Hard Curved Cabinet Scrapers Hardened to HRC 48-52 Edges milled to sharp 90 Suitable for immediate fine work Two thicknesses available 0.4mm(0.015") or 0.6mm(0.024") These Veritas scrapers are hardened to HRC 48-52 for increased durability, somewhat harder than most standard scrapers. In addition, their edges are carefully milled to a sharp 90 and are suitable for immediate fine work whilst heavier work only requires a slight hook to be burnished onto their edges. Available in two sets of three curved scrapers, either 0.4mm(0.015") or 0.6mm(0.024") thick.
