<p>The machine (1) has foldable gripping units, and an interchangeable assembling tool (5) including an open groove (16) whose curvature is homothetical to a curvature of a cutter blade to be sharpened (6), where the groove is provided with an S-shaped portion (20). The groove is co-operated with two removable guiding units that are fixed on top of a horizontal upper plate (3) to manually and alternatively displace an assembly constituted by the tool and the blade, which is supported on the plate and the guiding units along the groove, using a handle (17). An independent claim is also included for a method for sharpening a cutter blade.</p> |
