I found this online at the Silhouette School.
The black adapter is for the black ratchet blade
The blue adapter is for sketch pens
The gray adapter is used for the Silhouette Deep Cut blade
The white adapter is for the 2mm CAMEO 3 Kraft blade
Each adapter has a 1 on the front as a reminder it can only be used in CAMEO 4's Carriage 1 - the left side.
