In the industry they are called 'steel rule dies' and are the same as the ones that your printer uses when they need a fancy cut on a paper item. Unfortunately, the industry standard is around 1", which is what the Studio uses. The steel blades are all manufactured to this thickness. The die fabricator buys them, bends them to the appropriate shape and imbeds them into the wood backing. I've had dozens of dies made by various companies, but they all are the thicker variety. Sizzix dies are also a different thickness than what the Go and Go Baby can handle. I've never investigated, but if Accucut doesn't make them, I think you are out of luck, but you could try google-ing 'steel rule dies'. Make sure that you tell them the thickness you are looking for.
