I needed this ruler for measuring and model making. This is for checking permissions. This marking is very good even down to 1/100". readable. It has four scales. One side is fractions of an inch of 32 and 64 which you can easily use as a traditional imperial ruler as each 1/8" is a longer division. The other side is in 1/10" and 1/100" both Pages are in inches making them suitable for engineering and machinist work This is a high quality metal with an anti-reflective satin finish When tilted on the horizontal axis the numbers appear to disappear leaving a ghostly image that can still be read almost like a holographic effect This is probably my prettiest line I have no complaints about this line and I haven't seen any better compared to other expensive lines in the $10-$20 range I would like a triangular engineering ruler with an accuracy of 1/100 inch.
