Customer Reviews: Perfect straight edge for very little moneyJune 13, 2010 Corey H. Perez(Fairbanks (AK)) This straight edge was perfect for what I needed. I was redoing a top end of an engine and needed to check the major components for true. This worked perfectly for that purpose. Comes in a robust cardboard sleeve with a plastic slip on protective sleeve to ensure the machined surface doesn't become damaged.
