They are mounted onto rotating knife assemblies to chop, slice, and level raw sugar cane stalks, reducing them into smaller pieces for efficient juice extraction in subsequent mills.

They face severe abrasive wear from soil, silica, and sand embedded in raw cane; hardfacing and carbide tips protect the softer base steel from rapid erosion and dulling.

Knife tips are designed to slice and chop stalks cleanly using a sharp edge, whereas fibrizor hammers rely on blunt, high-impact force to tear and shred cell structures open.

They are typically secured using high-strength bolts, rivets, or welded joints depending on the specific design of the cane knife hub and maintenance preferences.

Ingested foreign objects like rocks, metal debris, railway spikes, or dry wood can cause severe chipping, while fine silica sand accelerates abrasive edge wear.
