✕DO NOT FORCE THE FIT
- Heavy wide-belt splicing and thick rubber. The .065" gauge flexes where the .083" eight-inch knives (60810/60780) drive through without chatter. Match the gauge to the belt.
- Deep bun foam. Flat grind; the hollow-ground knives own dense foam.
- A reason to drop pull-line discipline. The guard stops the cutting hand, not a bystander or the off hand.
- Scraping, prying, striking — a ground edge in a wooden handle.
- Flooring over a subfloor that must survive — the 67090 hook knife's captured-throat job.
