This 2 in 1 tool allows you to stitch over the 'hump' (thick part) of a seam as well as using the point of the tool to push fabric to a crisp point.
Tool 1 - Solves the frustration of stitching over the 'hump' thick part of a seam. Keeps the presser foot horizontal allowing for consistent even stitching. Helps eliminate skipped or uneven length stitches and broken needles. Also ideal when edge stitching collars and cuffs when there is little fabric resting between the foot and feed dogs.
Tool 2 - Use the point of tool to push fabric to a crisp point, such as collar edges, facings etc.
