This blade pairs with the Barry King Stitch Groover Handle (#123017, sold separately). A Stitch Groover creates a channel on your leather surface for the thread to sit in. It's an incredibly useful tool for both hand stitching and machine sewing leather. Use it to mark where to stitch so you have a straight line to follow. The thread then nests in the channel and lays flush with the surface of your leather, reducing any potential chaffing and wear and tear on the thread.
