Quick tip for bad trash bags

Not long ago I bought a roll of tall kitchen bags that were terrible! Every time I tried to separate the bags at the end where two "tops" join, they'd tear straight down, rendering the bags useless.

I wrote to Glad and they sent me a coupon for new ones, but I have a hard time throwing anything away. I started opening them with a scissors, trying to follow the dotted line, but they still tore when I tried to open them.

Then I noticed my paper cutter sitting there. Now I slice off the offending parts and the bags work fine... no little cuts and tears on the top to start a downward tear.
