The scalloped slicing knife does, thanks to its long and slim blade, not stick. Thanks to the dimples of the blade air cushions are formed by cutting with the scalloped slicing knife. Like this you can avoid that sticky products like ham adhere to the blade.
By cutting you should use the whole lenth of the blade of the scalloped slicing knife off the reel. Like this roasts or terrines can be cut finely and neatly.
