This is an excellent starter package, with three straight and three curved-edge orange blades as well as a compact holder (2 3/8" long). An ideal addition to every kitchen utility drawer, as well as being useful in the shop.
Originally developed for the graphics and auto-detailing industries, the blades are made from a material with natural lubricity. Soft enough to be used on non-stick cookware, automotive paints and other delicate surfaces, they resist common solvents and are slightly flexible.
The straight-edge version conforms to gently contoured surfaces, such as a car window or boat hull.
Not just for concave surfaces, the curved blade keeps the blade corners off the surface and allows for more control at the scraping edge. It can be used with a natural rotating action, varying the pressure and angle of attack.
