I can't live without mine! Have two of the standard size with half inch slots. I also have a third one that I dropped and broke then salvaged with duct tape because its like throwing away an old friend! I still use it sometimes. LOL. I also have the 1/4 cut which I don't care for very much. Its just as easy to shift the standard over half a notch to cut 1/4 or 3/4 measurements, and it's not big enough for much of the stuff I make. Last week I treated myself to the large one and I'm like a kid of Xmas. The Shape Cuts are also invaluable for straightening blocks before setting them into rows, and for resizing HST,as well as cutting blocks or strips. Three things I can't live without... Coffee, chocolate and my Shape Cuts. :o)
