The shape cut is the one that cuts in 1/2" increments. There is a smaller one (about half the size) that cuts 1/4".n I got both at Joanns with 40% off coupon. The shape cut will cut fabric across the grain if it is folded in half . That is how I use it all the time.. The shape cut I am talking about is the third one over on this page. I didn't see the smaller one but didn't look too hard. I know Joanns carries them.
