Tersa

Tersa replacement knives in HSS, M-Plus (M42), and carbide-tipped grades — reversible for two edges per knife, covering solid hardwoods and softwoods through abrasive man-made stock.

The system is self-locking: knives seat by rotation as the head comes up to speed, so a change involves no screws, gibs, or setting. Stocked lengths run to 640mm.
