Query: BIG disappointment!

Someody forgot to harden the steel used in these knives. The previous Delta knives lasted for 1000s of feet of use...I was lucky if I got 1000' w/ these, even with flipping them. Knots never have been a problem. With these knives pine knots dinged them repeatedly. Don't waste your $.
