d6 [Size] 2.0mm Total length: Approximately 15.5cm [Material] Stainless steel [Edge Creaser] An edge creaser is a tool used in leathercraft for edge finishing, where the heated creaser is pressed against the edge. This creates a parallel line on the edge, enhancing its appearance and also strengthening the fibers of the leather through burning, increasing durability. [How to Use] First, heat the edge creaser to the appropriate temperature with an alcohol lamp, melt wax, and apply it to the edge. The wax can be thread wax or edge wax, etc. Then, heat the edge creaser again and apply the creasing. It's often called a decorative crease, and its appearance changes depending on the skill of the user. *Using wax is also a matter of preference. [Notes] The size refers to the width of the tip; smaller sizes are suitable for thin leather, and larger sizes are suitable for thick leather. We recommend choosing a size that is easy to use based on the thickness of the leather being used and the distance from the stitching to the edge. The heat control is difficult, so it's a good idea to practice on scraps of vegetable-tanned leather. *Due to being an imported product, there may be minor scratches or slight stains during the manufacturing process. Please understand this beforehand.
