In an independent test, Morbark® knives, on average, scored much higher than competitive knives on sharpness and durability! Sharper knives mean more production and a better end product. Greater durability means increased wear life and reduced cost and replacement time. Both mean a better bottom line for your operation! Morbark sets a high standard for the quality of our chipper knives, giving you the edge you need to be more productive in your daily chipping operations. We carry knives for current and previous Morbark models, including single‑edge, double-edged and Babbitted styles. We also carry many knives for competitive models.
