I know these have been covered before but I just finally got around to getting a flat back 16 footer and it is easily the best 8 dollars I have ever spent in my life. The pencil sharpener is great the side that you can right on is great and this thing makes it so easy to make really accurate marks that you just can't do with a regular tape. The dummy readings in 16/ths really helps me out. My only complaint and it is a minor one is I wish that it was top and bottom american since I have no clue what the metric system is and have no use for it. http://www.woodcraft.com/PRODUCT/200...FUcCQAodCUgAKA
