This tool enables precise scribing of shelves, worktops and flooring through five different tracing wheels. The spring-loaded pencil, contained in the knurled shaft, allows gentle downward pressure and therefore a smooth, even line. Four tracing wheels can be fitted onto the freely rotating internal wheel and are held in place by an ‘o’ ring. The cap on the top forms the fixed 5th tracing wheel. For this set-up the pencil is inserted upside down in the shaft. Tracing wheel diameter 90 / 70 / 50 / 29 / 18 mm.
