Craftool� stamps are an investment that will last for years to come! In most types of carved leather designs, the beveler tool brings the design into three-dimensional relief. Using this tool correctly, along with proper moisture content of your leather, produces a nice burnishing (darkening) effect around your design. Our book, "Tech Tips" #66056-00 by Al Stohlman, illustrates "correct" and "incorrect" examples of beveling. Approx. stamp dimensions: 5/32x5/32.
