Steel Rule Set

This handy set of five steel rules is made from 1mm thick stainless steel, in 1/8", 1/4", 1/2", 3/4" and 1" wide strips all of which are 18" in length. The narrow rules are used as guides for evenly spacing out boards when building book and box covers, insuring perfect even hinges every time. The wider rules are used for trimming turn ins to create even turns on all sides. A very clever set, and a necessity to any bookbinders toolbox.
