<p>The multipurpose tool, designed to be fitted to the end of a straight handle, consists of a frame (1) of 1 cm angle iron with pointed ends and nine tines that project on both sides of it. On one side the tines all project for the same length to act as a rake, and on the other they form five long (2) and four short (3) tines that allow the soil to be worked at different depths. The long tines are curved at a well-defined angle. The tool can be made in two versions of different widths - 45 and 22 cm - which have different numbers of teeth.</p> |
