As an avid woodworking enthusiast, I was blown away by the immense utility that this product offers. Industrial and Scientific in its design, this measuring instrument is perfect for measuring curves and contours accurately. As a result of my tests, I determined that it works equally well on both convex and concave surfaces. The only downside is that it cannot be used on flat surfaces. Overall, this is an incredible tool that offers unmatched versatility in terms of measuring curved surfaces at an unbeatable value.
