Oregon sharpening standard is called 30-30 Which means sharpened at a 30 degree angle with a 30 thousands blunt edge. It is not recommended to put a knife edge on a blade because that edge wears down very quickly and will be at 30 thousands within a short period of time therefore no reason to remove more metal then requires.People,
Got 2 new Oregon blades for my MTD mower. They are pained black with high gloss paint. And the edge doesnt seem sharp when I run my finger across it. Is this normal?
Thanks.
