That’s right. Hard wood will cause sparks. I once ran a piece of pecan lumber through my table saw. There were sparks everywhere. Pecan is hard as hell.
Yep! WHn would is hard , it tales of miniscule steel chips from the blade, and the sparks are visible.
I used to split wood ocassionally at 30 below zero fahrenheit. The axe would spark almost every time.What’s more, you have to keep sharpening the axe more frequently in that kind of cold weather.The harder the steel, the more brittle it gets with the cold and the more it sparks.
Soft carbon steel axes make better cold weather wood choppers.
I bet that pecan wood smelled good on the table saw!
