I have found the 12 inch Incra rule of very good quality and precision. It is made of thin metal so as very fine holes have been pressed or laser cut into the metal. This makes the rule easy to bend, so I have made a box with plastic lid to protect it from being damaged, also putting 0.5 mm mechanical pencil in with rule as that is the size that fits the holes. Good product. KM.
Loved this purchase. The ruler has holes so you can precisely mark and pinpoint a position. Because its made of stainless steel, it won't bend and throw off your measurements, so everything gets marked with fantastic accuracy.
