Lacing chisels are specialised tools used for punching evenly spaced holes in leather or other materials to create a laced or stitched design. They typically have multiple prongs or teeth that can be adjusted for different spacing and thicknesses, and can come in a variety of sizes and shapes to accommodate different projects and designs. Lacing chisels are commonly used in leatherworking, but can also be used for other crafting or sewing projects that require precise hole spacing.
