Guys were talking about using their chainsaws for cutting the big hay bails. They showed pics. You know the way everything today is. Got to have pics. 
I told them about your paper rolls AND 090.
There was some farmers back in the day near me who cut those big round hay bails with big saws.
I never tried bales but I can reassure you anything harder to cut then those paper rolls would be a petrified tree, Lol.
