K
 Knife-Edge The knife-like profile of an edge.
Knife-Edged Follower A follower whose contacting surface with the cam is shaped like a knife. With knife-edged followers, the motion curve comes directly from the profile of the cam. Accordingly, the follower wears easily and, therefore, in practical use, the tip of the follower is dulled 1 mm to 2 mm.
