Review on Cullaby Contour Gauge: 10 & 5 Inch Duplications For Perfect Templates Of Curved And Odd Shapes, Plus Bonus Angle Ruler & Carpenter Pen! by Logan Barela

It's a very strong tool!The only issue that I experienced with my tight application was that since the gauge is thicker than the traditional ones it did not get into a tight space. I reversed the tool and use the other side hoping that the long side of the angled end was going to end up on the other side of my space. So to be more clear the improvement that might be made is this: the long ends of the angled edges should not end up on the same side when you reverse the contour tool. It is true that a situation like mine might be very rare but honestly I bought this tool only for this tight application.
