I love the new 3/8" size!! Sometimes the 1/2" is just a little bigger than I like on cards, etc. The 1/8" is a really small curve but it will serve a purpose, too.
Unlike another review, my Crop A Dile was marked correctly. The markings are painted on the "flaps" now vs. being etched in the metal so the pain may wear off, but right now the paint is much easier to see than the etching.
I use both the original and this new Crop A Dile all the time as "go to" tools.
