the no razor marking with the knife in it is good though.That's one of fastest ways to dull your knife....
cardboard eats edges fast but ductboard is the worst. the fiberglass kills the edge on any steel in no time. literally 1 cut. only the geometry allows cuts to still be made. hair wilting after fiberglass ductboard......no way.
