I have the Shape Cut, Shape Cut Plus, & Stripology, and mostly use the first two. The Shape Cut I've had for years, and I use it mostly when I'm not making alot of strips and the Plus when I have to cut alot of strips since its 18". I marked both with a nail polish dot at the 2.5" intervals since this is the most frequent cut I make & this makes cutting several strips at once much easier since I can see right away which slots to use. I'll use the Stripology occasionally, but prefer the JT rulers.
