Features three functional edges. The first 3.5″ linear edge is great for lifting bottom rollup gaskets while tucking the film safely beneath to reduce peeling. A long slender acute point works for reaching into tight corners of quarter windows and behind front and rear gaskets of roll-downs. The opposing 18″ radius edge is also 3.5″ wide and also functions well for lifting and tucking. The 1.95″ third edge features a 4″ radius blade that fits tighter curvature situations and is a good pressure concentration blade.
