When you cut cake for slices ,you know when you cut down to bottom to remove slice,well i seen where people bring their knife straight out towards the body and seen others bring knife angled up some and out when they remove knife. Both done with serrated knifes and cake knifes and chef knife too. would you know why or when you would do either of the those actions ....straight out to body to remove knife or angled up some knife to remove knife. The knife doesnt matter when you do these actions. Any advice appr.
