Damn it. I’m completely sorry for leaving out that detail. The knife, assuming you’re holding it in your right hand, will pull across the cracker from front to back. If any butter remains on the knife I just use the edge of the cracker to remove it. If the knife is in your left hand you will go in a counter clockwise motion to both remove the butter and smear it over the crack. Lefties are just weird in that way. Thanks for the comment!
