A million uses (01 May 2010)
Well that might be an exageration but this ruler is the bomb diggity. It's sturdy enough that you can use it to tear paper, clear so you can see precisely what you are working on and where you are on your project. The numbers and lines are clear and easy to read. There are also punch holes which are GREAT! 12 inches of punch holes. It makes doing a straight line of almost any size easy peasy.
Best money I ever spent on a tool.
