Ice Shaver: Blades

My replacement ice shaver blade doesn't look like my original. Why?

Our shaving blades for ice shavers have been redesigned beginning with date series 0918. The new style replacement, U28-38, will fit all S660, SIT4660, SIT466LP and SIT18003 ice shavers. If ordering a replacement blade, keep and use existing your screws; ice shavers with date series before 0918 need two screws to attach, after 0918 only require one. The replacement blade comes with one screw.
