I have lots of unused ones also. I keep figuring when I retire I will have more time to "play" with them. Like others have stated, I'm glad I got them when they were available and for a good price. I usually get my rulers when they are on sale. I always seem to need to replace my 6 x 24. I guess I use it so much that the sides aren't straight any more. I do rotate the ruler so I am using all four sides as my straight edge. Does anyone else have that problem?
