Meet Chevy, a machine quilting tool designed by Angela Walters.
Chevy is a little pointy, a little curvy, and very versatile.

Curved edges allow for versatile designs
Use the straight side for: stitching in the ditch and echoing; turning the corner without rotating the ruler; echo quilting two sides of a block without marking the pivot point; adding chevron designs all over a quilt, or as a border.
Use the curvy side for: adding a subtle, curvy line; stitching offset, rounded rectangles by changing direction; creating a modern, all over wavy design; creating fun quilt motifs for blocks or segmenting borders
