If you’re opening a jar with a two-piece vacuum sealed lid, such as a Mason jar, you’ll have to take the ring band off first. Ideally, the ring band should have been removed immediately after the jar was sealed. If not, you might need to use a rubber grip or manual jar opener to get it off. Next, use the edge of a spoon or the blade of a butter knife to lever off the flat lid. If that doesn’t work, try a church key or bottle cap remover, but take care not to chip the glass.
