3M Hand-Masker 12-Inch Paper Blade, PB12, for use with 3M Hand-Masker M3000 or M1000-SB Tools

can you cut brown paper as well?

Will the 12” blade cut the 3M 99”x90’ film roll?

Are their screws to hold the blade on, or does it just lock into the hand masker? If there are screws which order do they come with?

Paper weighs more than plastic. Is the tool sturdy enough to hold a roll of 12" masking paper?
